Reign of Dragons Upgrade Guide: Best Lathliss Upgrades

Reign of Dragons is one of the most spectacular Commander precons in the Foundations lineup. Its strategy is refreshingly straightforward: accelerate into enormous Dragons, fill the battlefield with flying threats and overwhelm opponents before they can recover. But while the original deck has plenty of power, it also suffers from the problem that holds many casual Dragon decks back — too many expensive creatures and not enough ways to cast them quickly.

Led by Lathliss, Dragon Queen, the mono-red precon rewards every nontoken Dragon entering the battlefield with an additional 5/5 flying Dragon token. That makes cards like Dragon Tempest, Scourge of Valkas and Utvara Hellkite especially threatening, and all three are already included in the original deck.

The best Reign of Dragons upgrades therefore aren’t simply more expensive Dragons. The deck needs better acceleration, more efficient threats and ways to turn each Dragon entering the battlefield into additional resources.

Our top recommendations are Ganax, Astral Hunter, Roaming Throne and Cavern-Hoard Dragon. They strengthen the deck without changing its identity, while more affordable additions can make a noticeable difference even on a small budget.

Here’s how we’d upgrade Lathliss, which cards we’d remove and where we’d spend our money first.

Best Reign of Dragons Upgrades at a Glance

You don’t need to rebuild the entire deck to make Reign of Dragons significantly stronger. The original list already contains several excellent Dragon tribal staples, so our priority is improving consistency and making the existing threats more effective.

If you’re upgrading the deck gradually, begin with mana acceleration before spending heavily on additional finishers. Lathliss is already capable of winning games with the Dragons included in the box. Getting her onto the battlefield earlier is often more impactful than adding another expensive creature.

How Lathliss Turns Every Dragon Into Two Threats

Lathliss, Dragon Queen costs and enters as a 6/6 Dragon with flying. Whenever another nontoken Dragon enters under your control, she creates a 5/5 red Dragon creature token with flying. Her additional ability lets you pay to give all Dragons you control +1/+0 until end of turn.

That combination makes Lathliss an excellent commander for players who enjoy straightforward tribal strategies with explosive turns.

The important word in her triggered ability is nontoken. The Dragon token created by Lathliss won’t trigger her again, so the effect doesn’t create an infinite number of Dragons by itself. Instead, every actual Dragon entering the battlefield produces an additional flying threat.

This becomes especially powerful when you combine Lathliss with cards that reward creature entries. Dragon Tempest can give your flying creatures haste and deal direct damage when Dragons enter, while Scourge of Valkas deals damage based on the number of Dragons you control.

Because Lathliss creates another Dragon whenever you cast a nontoken Dragon, both the original creature and the resulting token can trigger your other Dragon payoffs.

The deck can therefore deal substantial damage without needing to attack, although combat remains its primary route to victory.

Best Creature Upgrades for Reign of Dragons

Ganax, Astral Hunter – The First Card We’d Add

Ganax, Astral Hunter is arguably the most natural upgrade for this Commander deck.

Whenever Ganax or another Dragon enters under your control, you create a Treasure token. This means that a single Dragon entering while Lathliss and Ganax are on the battlefield can generate two Treasures: one from the original Dragon and another from the token Lathliss creates.

Those Treasures help cast additional Dragons, which can produce more Treasures and continue developing your battlefield.

This addresses the precon’s biggest weakness. Instead of spending an entire turn casting one expensive creature, you can gradually generate enough resources to deploy multiple threats in succession.

Ganax is also a Dragon himself, so he works naturally with the tribal payoffs already included in the deck.

Our recommendation: Make Ganax one of your first additions. He improves both the mana engine and the core Lathliss strategy.

Roaming Throne – Double Your Best Dragon Triggers

Roaming Throne is one of the most powerful upgrades available for Reign of Dragons.

When it enters the battlefield, choose Dragon as the creature type. Triggered abilities of other Dragons you control will then trigger an additional time.

Most importantly, Lathliss herself is a Dragon, so Roaming Throne allows her token-creation ability to trigger twice whenever another nontoken Dragon enters under your control.

Instead of creating one 5/5 Dragon token, you’ll create two. That’s ten additional flying power from a single creature entering the battlefield.

Roaming Throne also makes cards such as Scourge of Valkas and Thunderbreak Regent more dangerous by multiplying their relevant triggered abilities.

The interaction with Ganax, Astral Hunter is particularly impressive. Additional Dragon entries generate even more Treasure tokens, allowing you to continue casting spells.

Although Roaming Throne isn’t inexpensive, it offers more than simply adding another Dragon. It improves many of the cards already present in the deck.

Cavern-Hoard Dragon – A Threat That Helps Pay for Itself

Cavern-Hoard Dragon has an expensive printed mana cost, but that doesn’t necessarily mean it will be difficult to cast.

Its affinity for artifacts reduces its generic mana cost based on the number of artifacts your opponents control. In multiplayer Commander, Treasure tokens, mana rocks and other artifacts are common enough that Cavern-Hoard Dragon can become significantly cheaper than expected.

Whenever it deals combat damage to a player, it also creates that many Treasure tokens.

That gives Reign of Dragons another source of acceleration attached to a threatening flying creature.

With Lathliss already on the battlefield, Cavern-Hoard Dragon also creates an additional 5/5 Dragon token, making the overall exchange even more attractive.

Our recommendation: Cavern-Hoard Dragon is an excellent middle-ground upgrade for players who want both larger threats and better resource generation.

Ancient Copper Dragon – The Premium Finisher

Ancient Copper Dragon offers enormous potential, but it’s a luxury rather than a necessity.

Whenever it deals combat damage to a player, you roll a d20 and create that many Treasure tokens.

Even an average result can generate enough mana for multiple follow-up spells, while an exceptionally high roll can turn the next turn into something spectacular.

Combined with Lathliss, Dragon Tempest and other Dragon payoffs, those extra resources can quickly lead to a battlefield that opponents struggle to answer.

However, Ancient Copper Dragon is vulnerable to removal before it connects, and its price can represent a substantial part of an upgrade budget.

I’d prioritize Ganax and Roaming Throne first, then consider Ancient Copper Dragon once the deck already develops consistently.

Improve the Ramp Before Adding More Dragons

Reign of Dragons already contains several excellent finishers. Utvara Hellkite, Drakuseth, Maw of Flames, Scourge of the Throne, Terror of Mount Velus and Skyline Despot provide more than enough late-game power.

The problem is reaching the late game with enough resources to use those cards effectively.

Fortunately, the original precon includes Dragonlord’s Servant, Dragonspeaker Shaman and Herald’s Horn. These are excellent tribal cost reducers, and I’d preserve all three.

Dragon’s Hoard is another important piece. In addition to producing mana, it can accumulate gold counters when Dragons enter and convert those counters into card draw.

The strongest upgrades complement these existing cards rather than replacing them.

Mind Stone – Simple, Effective Acceleration

Mind Stone costs two mana, provides one colorless mana and can later be sacrificed to draw a card.

It isn’t flashy, but that’s exactly why it works here.

Replacing a slower three-mana ramp spell with Mind Stone can help the deck reach its important turns earlier. Its ability to turn into another card also makes it less disappointing when drawn late in a game.

For a relatively modest investment, it’s a useful improvement.

Wayfarer’s Bauble – Another Reliable Mana Source

Wayfarer’s Bauble is another reasonable budget option for a mana-hungry mono-red strategy.

It lets you search for a basic land and put it onto the battlefield tapped, giving the deck access to permanent mana development rather than relying entirely on artifacts that opponents may destroy.

Bauble isn’t as explosive as Treasure-based acceleration, but it improves consistency without requiring complicated interactions.

Goldspan Dragon – The Premium Ramp Option

Goldspan Dragon combines aggressive pressure with powerful Treasure generation.

It creates Treasure when it attacks or becomes the target of a spell, and the Treasures you control can produce two mana of one color instead of one.

That makes Goldspan especially useful alongside Ganax, Astral Hunter and the Treasure-generating abilities of other upgraded Dragons.

With enough Treasure production, the deck can begin casting multiple expensive Dragons during the same turn.

Goldspan Dragon is a strong premium option, but unlike Ganax, it’s not essential to making the strategy function.

What Cards Should You Cut From Reign of Dragons?

The stock deck has a solid Dragon core, so I’d avoid removing its strongest tribal pieces just to make room for more expensive creatures.

Instead, focus on slower mana sources and Dragons that offer relatively little value compared with their cost.

These are starting recommendations, not mandatory replacements. Some cards can be more valuable in particular playgroups, and your preferred version of Lathliss may emphasize different interactions.

Commander’s Sphere is an obvious candidate because three-mana ramp is relatively slow in a deck that wants to accelerate toward a six-mana commander. Mind Stone can help deploy key creatures and cost reducers sooner.

Firespitter Whelp benefits from being a Dragon, but Ganax contributes far more to the overall engine. Treasure generation helps cast additional threats and creates meaningful advantages in longer games.

Tyrant’s Familiar is a large threat with potential removal attached, but at seven mana it competes with several other expensive Dragons. Cavern-Hoard Dragon is generally easier to deploy against artifact-heavy tables and creates additional resources when it connects.

The land replacement is straightforward. Temple of the False God cannot produce mana until you control at least five lands, making it particularly awkward in opening hands. Another basic Mountain is less exciting but considerably more reliable.

Finally, Parapet Thrasher is a reasonable flex slot if you’re looking to add Roaming Throne. Doubling Lathliss’s triggered ability has a much greater ceiling than another conventional creature.

I wouldn’t cut Dragon Tempest, Scourge of Valkas, Utvara Hellkite, Dragonspeaker Shaman or Dragonlord’s Servant. Those cards already form the strongest part of the deck.

Budget vs. Premium Reign of Dragons Upgrades

Reign of Dragons can improve considerably without purchasing every expensive Dragon on the market.

In fact, making the deck faster will often do more for its performance than simply increasing the quality of its top-end creatures.

Budget Upgrade Path

For a lower-cost upgrade, prioritize Ganax, Astral Hunter, Mind Stone and Wayfarer’s Bauble, depending on current card prices.

Ganax reinforces the main Dragon strategy while producing useful Treasure tokens. Mind Stone provides inexpensive acceleration, and Wayfarer’s Bauble offers additional land development.

Another useful consideration is Thrill of Possibility, which is already included in the stock deck. Rather than replacing it immediately, preserve this kind of filtering until you’ve added enough other sources of card advantage.

I’d also retain Unexpected Windfall. Four mana is a meaningful investment, but drawing cards while producing Treasure tokens suits a mana-hungry Dragon strategy.

The goal isn’t to turn Reign of Dragons into a completely different deck. It’s to make the existing strategy function a turn earlier and reduce the number of opening hands filled with uncastable Dragons.

Premium Upgrade Path

If budget is less of a concern, I’d move toward Roaming Throne, Goldspan Dragon and Ancient Copper Dragon.

Roaming Throne improves Lathliss herself, Goldspan Dragon makes Treasure generation considerably more powerful and Ancient Copper Dragon offers an enormous payoff when it connects with an opponent.

Another spectacular option is Dracogenesis, an enchantment that lets you cast Dragon spells without paying their mana costs.

Dracogenesis is expensive to deploy, but once it resolves, it can transform a hand full of enormous Dragons into an explosive sequence of creature entries and Lathliss triggers.

It’s the kind of card that makes a strong deck memorable, although I wouldn’t prioritize it over ramp and consistency.

Our buying recommendation: Start with a few affordable improvements, play several games and identify the situations where the deck struggles. Invest in premium Dragons only after those weaknesses have been addressed.

Keep These Cards From the Original Precon

One of the strongest selling points of Reign of Dragons is that its original decklist already contains many cards that belong in a properly upgraded Lathliss deck.

Dragon Tempest is one of the most important. Granting haste to flying creatures and dealing damage when Dragons enter allows the deck to convert its creature production into immediate pressure.

Scourge of Valkas provides another powerful damage engine. Because it counts Dragons you control when its triggered ability resolves, the battlefield can become increasingly dangerous as Lathliss creates additional tokens.

Warstorm Surge offers a similar form of direct damage, triggering whenever a creature enters under your control. It’s expensive, but extremely powerful when every nontoken Dragon also creates an additional 5/5 token.

Utvara Hellkite provides another impressive source of Dragon tokens. Whenever a Dragon you control attacks, Utvara Hellkite creates a 6/6 flying Dragon token. Unlike Lathliss, this ability doesn’t require you to cast additional Dragons.

The original deck also includes several useful ways to improve consistency. Herald’s Horn reduces Dragon costs and offers potential additional cards, while Dragon’s Hoard provides both mana and card advantage.

Even creatures that look less spectacular can be essential. Dragonlord’s Servant and Dragonspeaker Shaman are precisely the cards that help ensure your larger Dragons arrive before opponents have already taken control of the game.

These are the cards I would build around rather than replace.

How to Upgrade the Mono-Red Mana Base

Reign of Dragons is easier to improve than many multicolored Commander decks because it doesn’t need expensive mana fixing.

The original list includes 32 Mountain cards alongside utility lands such as Haven of the Spirit Dragon, War Room, Bonders‘ Enclave, Spinerock Knoll and Forgotten Cave.

Most of these are worth keeping.

Haven of the Spirit Dragon helps cast Dragons and can later return a Dragon creature card from your graveyard to your hand. War Room provides additional card draw, which is particularly useful when your deck contains so many expensive spells.

Spinerock Knoll can also provide excellent value in games where you deal a substantial amount of damage during one turn.

The first land I’d remove is Temple of the False God. It produces two colorless mana once you have enough lands, but it is unreliable early and can make opening hands more awkward.

A basic Mountain is a perfectly reasonable replacement.

For players who want a more ambitious mana base, Valakut, the Molten Pinnacle offers an additional source of damage once enough Mountains are available.

However, I wouldn’t overload the deck with lands that only produce colorless mana. Reign of Dragons needs consistent access to red mana, both for casting its creatures and activating Lathliss’s ability.

How the Upgraded Reign of Dragons Deck Wins

The ideal game begins with acceleration rather than enormous Dragons.

Cards such as Sol Ring, Arcane Signet, Dragonlord’s Servant and Dragonspeaker Shaman help establish the mana needed to cast Lathliss ahead of schedule.

Once your commander enters, the goal is to follow her with another nontoken Dragon as quickly as possible.

Ganax, Astral Hunter is especially effective in that role. He creates an additional Dragon through Lathliss while producing Treasure that helps cast your next spell.

With Dragon Tempest on the battlefield, those Dragon entries can also generate direct damage. Scourge of Valkas increases that pressure even further.

The deck becomes especially dangerous when you add Roaming Throne. Doubling Lathliss’s token-creation ability means every new nontoken Dragon can produce two additional flying creatures.

Once you’ve developed several Dragons, Utvara Hellkite can turn combat into another source of token production.

There are also opportunities for explosive finishing turns. Terror of Mount Velus can give your creatures double strike, while Warstorm Surge converts creature entries into additional damage.

Against slower opponents, this combination can overwhelm the battlefield remarkably quickly.

However, the deck is still vulnerable to removal. A board wipe immediately after deploying Lathliss and several expensive Dragons can leave you without enough resources to recover.

That’s why I wouldn’t eliminate the deck’s card filtering and mana acceleration just to squeeze in another powerful creature. The best version of Reign of Dragons is the one that can rebuild and continue playing after its first wave of threats is answered.

Is Reign of Dragons Worth Buying or Upgrading?

Reign of Dragons is an excellent starting point for anyone who enjoys Dragon tribal, especially players who prefer straightforward combat strategies with plenty of explosive interactions.

The sealed precon already contains several cards that would normally be high-priority additions to a Lathliss deck. That makes it an appealing purchase for players who don’t own an established Dragon collection.

However, its value depends on the current sealed price and which cards you already own.

If you already have Dragon Tempest, Scourge of Valkas, Utvara Hellkite and other important Dragon staples, purchasing a few individual upgrades might make more financial sense than buying an additional precon.

For a newer player, the sealed product offers immediate playability, a complete mana base and a cohesive strategy without having to assemble a deck from scratch.

PreconForge Verdict: The Best Lathliss Upgrades

Reign of Dragons doesn’t need more expensive creatures nearly as much as it needs better ways to cast the Dragons already in the deck.

The stock list includes powerful tribal staples such as Dragon Tempest, Scourge of Valkas, Utvara Hellkite, Dragon’s Hoard and Dragonspeaker Shaman. Those cards form a strong foundation worth preserving.

Our first addition would be Ganax, Astral Hunter. He gives the deck a reliable way to turn Dragon entries into the mana needed for additional spells.

Roaming Throne is the most exciting way to improve the deck’s core ability, while Cavern-Hoard Dragon adds another threat that can generate resources without demanding its entire printed mana cost.

For budget players, improvements such as Mind Stone and Wayfarer’s Bauble can help smooth out the early turns. Higher-budget builds can explore Goldspan Dragon, Ancient Copper Dragon and Dracogenesis for spectacular late-game potential.

Most importantly, resist the temptation to solve every weakness by adding another enormous Dragon. Reign of Dragons already knows how to finish games. What it needs is the consistency to reach those winning positions more often.

Our final recommendation: Start with Ganax, Astral Hunter, improve your early acceleration and add Roaming Throne when your budget allows. Those changes make Lathliss faster, more explosive and considerably more difficult for opponents to contain.
