Be'lakor, the Dark Master + Dread Slaver + Xenograft + Archetype of Finality

Be'lakor, the Dark Master

Dread Slaver

Xenograft

Archetype of Finality

How it works

1. Cast Dread Slaver by paying 3.
2. When Dread Slaver enters the battlefield, Be'lakor's second ability triggers, causing Dread Slaver to deal damage equal to its power to itself.
3. Dread Slaver dies as a state-based action due to its deathtouch.
4. Dread Slaver triggers, returning itself from your graveyard to the battlefield.
5. Repeat from step 2.

This clever loop turns Be'lakor, the Dark Master into a self-destructive engine by leveraging Xenograft to turn every creature into a Demon as it enters. With Archetype of Finality granting your team deathtouch, Be'lakor's Lord of Torment trigger causes the newly entered Dread Slaver to deal lethal damage to itself. That lethal blow immediately satisfies Dread Slaver's own resurrection condition, pulling it right back from the graveyard to repeat the cycle infinitely.
