Best Monster Train 2 Pyre Hearts: Tier List & Unlocks

There are 13 Pyre Hearts: one default heart, nine progression unlocks and three awarded for defeating the Titans. Every current requirement is below, followed by exact game-data effects and a community ranking of the best hearts.

Quick verdict

What is the best Pyre Heart in Monster Train 2?

Pyre of Dominion is the best general pick in the current community consensus because it turns the starting deck into immediate, consistent power. Fhyra's Greed is the other top option when a run can turn Pyre damage into a durable Gold advantage.

Pyre of Dominion Remove Train Stewards and starting cards. Immediately draft four packs, and double each card picked.

Fhyra's Greed When your Pyre takes damage, gain 10 Gold.

Quick answer

How to unlock all 13 Pyre Hearts

Most counters carry across runs. Current patch values matter: older guides may still show 9 Trial wins, 275 Shifts, 15,000 Magic Power damage or 40 Frozen-card holds; patch 2.2.1 uses 7, 225, 12,000 and 25 respectively.

Starting heart

Available immediately; it is the baseline before any progression objective.

Proto Heartcage

Niche

Available by default on a new save.

It has no special effect, making it the baseline for comparing every unlock.

Nine progression unlocks

These objectives accumulate across runs unless the requirement says to win a challenge.

Heart of the Pact

Niche

Win 7 battles with Trials enabled.

The May 28 patch lowered this from 9 wins to 7. Only enable a Trial when your deck can absorb its downside.

Lifemother's Pyre

Strong

Take 475 total Pyre damage across runs.

The counter is cumulative, so ordinary leaks advance it even when the run is not a win.

Wyngh's Spirit

Situational

Shift units 225 times across runs.

Movement-heavy Banished decks advance this naturally. The May 28 patch lowered the target from 275.

Malicka's Shifting Pyre

Situational

Win a Dimensional Challenge.

Unlock two additional Pyre Hearts to open the Dimensional Portal, then clear any available challenge.

Fhyra's Greed

Top pick

Spend 20,000 Gold across runs.

The objective tracks Gold spent, not Gold earned. Merchants, upgrades and removals all help.

Aquath's Reservation

Situational

Deal 12,000 damage with Magic Power.

Prioritize high-Magic-Power and multi-hit spells. The May 28 patch lowered the target from 15,000.

Bogwurm's Growth

Situational

Inflict 3,200 Debuff effects across runs.

Repeatedly applying status effects is more useful for this counter than one large damage turn.

Echo of the Time Father

Situational

Hold Frozen cards in hand 25 times.

Keep Frozen cards through the end of a turn. The May 28 patch lowered the target from 40.

Herzal's Horde

Strong

Deal 10,000 damage with Train Stewards.

Upgrade and support Train Stewards instead of removing them. The current target is 10,000 after the May 28 patch.

Titan rewards

Each of these three hearts is awarded after defeating the Titans.

Pyre of Savagery

Strong

Defeat the Titans.

Unlock all nine progression hearts, then win all three Titan trials in one run to reach the fight.

Pyre of Dominion

Top pick

Defeat the Titans.

The same Titans victory awards this heart alongside Savagery and Entropy.

Pyre of Entropy

Strong

Defeat the Titans.

Pyre Heart tier list and exact effects

Effects come directly from the current game dataset. Ratings synthesize public tier lists and consistency discussions, so they are strategic consensus rather than game data.

Pyre Heart	Exact effect (game data)	Community view
Pyre of Dominion	Remove Train Stewards and starting cards. Immediately draft four packs, and double each card picked.	Top pick Tops most community lists — reshapes the starting deck into immediate, consistent power.
Fhyra's Greed	When your Pyre takes damage, gain 10 Gold.	Top pick Durable and always useful — turns hits on the Pyre into an economy.
Pyre of Entropy	Add a Vengeful Shard to your deck after each battle. Draw 1 extra card for every 2 Blights in your deck.	Strong A draw engine that rewards bigger decks and spare Ember.
Herzal's Horde	Gain 4 Deployment Ember. Deployable upgrade is X% cheaper.	Strong Cheaper, more reliable unit setups every battle.
Lifemother's Pyre	Adds the option to copy cards at the Merchants of Steel, Magic, and Trinkets.	Strong Shop copies of your key cards enable duplicate-driven builds.
Pyre of Savagery	Friendly units gain Slay: +1 Attack permanently.	Strong Attack that keeps scaling — community favourite with Slay payoffs.
Echo of the Time Father	Once per battle, select the Heart to apply Freeze to all non-Blight and non-Scourge cards in hand.	Situational High skill ceiling: guarantees your key turn when piloted well.
Bogwurm's Growth	Permanently add 1 Capacity to a random floor after each battle.	Situational Loved by space-hungry swarm decks; which floor grows is random.
Malicka's Shifting Pyre	All drafted cards appear with an upgrade.	Situational Upgraded drafts save gold, but upgrade quality varies.
Aquath's Reservation	Once per battle, select the Heart to gain 3 Ember.	Situational A flexible Ember burst — useful everywhere, spectacular nowhere.
Wyngh's Spirit	Once per battle, select the Heart to restore the front friendly units on all floors to full health.	Situational Strong early, fades as your runs start ending fights faster.
Heart of the Pact	After playing a card from your Primary and Allied clan, draw +X next turn.	Niche Divisive: a real draw payoff on a body many rate too fragile at high Covenant.
Proto Heartcage	No special capabilities.	Niche The default heart — baseline stats, no effect.

Sources, method and version notes

Unlock conditions are editorial data because those counters are not included in RailTools' committed game-data dump. They are cross-checked against the current wiki table and the patch notes that changed five targets. Exact effects come from the game files. Community ratings are consensus, not gospel: the right pick still changes with clans, Covenant level and deck plan.
