Dread Slaver + Flayer of the Hatebound + Mikaeus, the Unhallowed + Death Baron

Dread Slaver

Flayer of the Hatebound

Mikaeus, the Unhallowed

Death Baron

How it works

1. Kill Dread Slaver.
2. When Dread Slaver dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
3. When Dread Slaver enters the battlefield, Flayer of the Hatebound triggers, causing Dread Slaver to deal damage to itself equal to its power.
4. Dread Slaver dies as a state-based action due to its deathtouch.
5. Dread Slaver triggers, returning itself from your graveyard to the battlefield.
6. Repeat from step 3.

This clever loop relies on Mikaeus, the Unhallowed to grant undying to Dread Slaver, allowing it to return with a +1/+1 counter whenever it dies. That entry from the graveyard triggers Flayer of the Hatebound, forcing Dread Slaver to deal damage equal to its power to itself. Because Death Baron grants deathtouch to all Zombies—and Dread Slaver is naturally a Zombie, further pumped by Mikaeus, the Unhallowed and Death Baron—that self-inflicted damage instantly destroys Dread Slaver. This death immediately triggers Dread Slaver's own replacement effect to return it from the graveyard to the battlefield, restarting the cycle and fueling Flayer of the Hatebound for infinite damage.
