This guide focuses on low-effort, high-reward combos in Monster Train 2. These are not perfect RNG fantasy setups. These are builds that start working early, scale naturally across waves, and usually win even if the rest of the deck is mediocre.
The idea is simple: take one strong interaction and let the game carry itself.
Underlegion
Underlegion’s strongest champion path is borderline broken because it scales every single turn, not per wave, not per fight, but permanently. Colonel triggering Rally four times at end of turn means the champion gains raw attack continuously without needing kills, spells, or positioning tricks.
By the time you reach late game, this champion casually reaches 300–400 attack and deletes bosses alone. The rest of the deck barely matters. You just need to keep the champion alive long enough for the scaling to do its thing.
This is one of the safest solo-carry setups in the game.
Underlegion + Melting Remnant
This combo revolves around Baron harvesting stats from friendly deaths. Melting Remnant provides the fuel, Underlegion provides the payoff.
Funguy units die constantly. Each death feeds Baron massive attack and health. Once you add Multistrike and Smidgestone, the scaling gets ridiculous very fast. Multiple waves later, Baron walks into the final fight with absurd stats, often over 800 attack and hundreds of HP.
It feels slow at first, then suddenly nothing survives a single combat round.
Pyreborne
Pyreborne’s egg mechanic looks slow until you realize how easy it is to loop. Collect eight eggs using the champion or cheap spells, then upgrade the resulting dragon with Endless and Multistrike.
Every resummon makes the dragon stronger. Death stops being a downside and becomes the win condition. A few cycles later, you are staring at a 400+ attack dragon that refuses to stay dead.
This build wins by accident while you are still figuring out your deck.
Pyreborne + Melting Remnant
This is the same dragon strategy pushed into absurd territory. Burnout guarantees the dragon dies every turn. Endless or Reform guarantees it comes back stronger.
The result is constant scaling without effort. You are not defending the unit, you are farming its death. After a few waves, the dragon becomes a one-unit army that clears entire floors on summon.
It looks fragile on paper and feels unstoppable in practice.
Luna Coven
Luna Coven shines when you lean into room manipulation. Eclipse Chamber creating New Moon turns Shadeguards into stat monsters. Each wave adds raw attack and health, no conditions attached.
Add Multistrike and let the waves roll in. By the final fight, Shadeguards easily reach 500+ attack and delete everything before it touches them.
This build scales quietly, then suddenly ends the run.
Lazarus League
This setup abuses spell recursion. A unit with Largestone and Multistrike becomes the physical threat. A spell with Intrinsic and Holdover becomes the engine.
Every turn you cast the spell, gain attack, and get the spell back. No draw dependency, no setup turns. The attack gain stacks indefinitely and reaches absurd numbers long before the final boss.
If played cleanly, this build often hits 900+ attack without trying.
Banished
Banished works best when you stop forcing creativity and just lean into durability. Firebrand with Multistrike and Dualism scales naturally over waves. Duplicate equipment and spread it across units.
Armor generation becomes automatic. Health refills itself. After enough waves, you end up with units that regenerate, repair, and hit back harder every turn.
It is not flashy, but it is extremely hard for bosses to break.
Banished + Underlegion
This combo turns the game into a slow, inevitable grind in your favor. Max HP increases stack across the entire team. Regen heals everything back to full every turn.
The boss can hit for twenty turns straight and still not make progress. Meanwhile, Revenge damage climbs into triple digits and ends the fight eventually.
If you enjoy watching enemies fail to kill you, this build delivers.
Melting Remnant
Remnant Host with Endless and Burnout becomes a summon engine. Each death spawns multiple draffs. Each death feeds Baron harvest triggers.
Baron scales from friendly deaths and enemy kills simultaneously. After a few fights, the numbers stop feeling real. This build rewards careful positioning early, then plays itself.
High power, slightly higher attention, very reliable payoff.
Hellhorned
Hellhorned struggles overall, but this setup works consistently. Branded Warrior with Multistrike and Furystone snowballs attack every turn. Steelworker duplicated with armor upgrades turns the frontline immortal.
Armor numbers climb into the hundreds, and the Warrior punches through everything behind it. It is slower than top-tier builds, but stable enough to win most runs.
Stygian Guard – Spell Loop Siren
This build ignores traditional unit combat and focuses on spell repetition. Keep the deck tiny. Loop Offering Token to discard Guardian’s Amulet repeatedly.
Enemies lose all attack through Sap. Siren gains massive attack from repeated spell casting. Bosses eventually deal zero damage while the Siren reaches four-digit attack values.
It looks fragile, but once assembled, it is untouchable.
Awoken
Husk Hermit with Quick and Multistrike ends fights before enemies get a turn. Razorsharp Edge with Intrinsic and Holdover ensures permanent scaling every turn.
Duplicate the spell and the attack ramps fast. With Quick, survivability becomes irrelevant. Add a disposable Endless tank if corruption gets messy.
This is one of the cleanest, most straightforward win conditions in the game.
Umbra – Mega Snack Primordium
Primordium with Glass Cannon feeds absurd stats to the front unit every turn. Multistrike multiplies the value. Endless ensures the carrier never stays dead.
The numbers escalate extremely fast. Within ten turns, the front unit reaches 500+ attack, and the run is effectively over.
Umbra is inconsistent overall, but this specific setup is brutally effective.
Clanless – Dante
Dante deserves a mention because he breaks the rules. Quick turns him into a floor-clearing missile. Endless keeps him relevant forever. Flat attack upgrades scale faster than most clan mechanics.
If Dante shows up, he can carry almost any run regardless of clan choice.
Most easy wins in Monster Train 2 come from one strong loop, not complicated decks. Endless, Holdover, Multistrike, and death-based scaling are the real win conditions. Once one of these engines starts running, the rest of the run usually solves itself.
