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

Be'lakor, the Dark Master

Dread Slaver

Arcane Adaptation

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 loop turns Dread Slaver into an autonomous executioner by leaning heavily on Arcane Adaptation to name "Demon," causing every self-inflicted entry to trigger Be'lakor, the Dark Master. Because Archetype of Finality grants deathtouch to all your creatures, that damage dealt by Be'lakor's ability is lethal, immediately sending Dread Slaver to the graveyard. From there, the Slaver's own resurrection trigger pulls it right back to the battlefield, restarting the cycle for infinite death and entry triggers.
