Dread Slaver + Flayer of the Hatebound + Mikaeus, the Unhallowed + Ashnod's Altar

Dread Slaver

Flayer of the Hatebound

Mikaeus, the Unhallowed

Ashnod's Altar

How it works

1. Activate Ashnod's Altar by sacrificing Dread Slaver, adding CC.
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. Activate Ashnod's Altar by sacrificing Dread Slaver, adding CC.
5. Dread Slaver triggers, returning itself from your graveyard to the battlefield.
6. Repeat from step 3.
