Cauldron Familiar + Witch's Oven + Clock of Omens + Genesis Chamber

Cauldron Familiar

Witch's Oven

Clock of Omens

Genesis Chamber

How it works

1. Activate Witch's Oven by tapping and sacrificing Cauldron Familiar, creating a Food token.
2. Activate Clock of Omens by tapping the Food and another artifact you control, untapping Witch's Oven.
3. Activate Cauldron Familiar by sacrificing a Food, returning Cauldron Familiar from your graveyard to the battlefield.
4. When Caludron Familiar enters the battlefield, it and Genesis Chamber trigger.
5. Resolve the Cauldron Familiar trigger, causing each opponent to lose 1 life and you to gain 1 life.
6. Resolve the Genesis Chamber trigger, creating a 1/1 Myr artifact creature token.
7. Repeat.

This intricate machinery turns a humble cat-and-oven loop into an endless engine of attrition. By feeding Cauldron Familiar to Witch's Oven, you create a Food token that Clock of Omens immediately puts to work alongside another artifact to untap the Oven, fueling the cat's return from the graveyard. Every time Cauldron Familiar re-enters the battlefield, Genesis Chamber spots the new arrival and obligingly manufactures a 1/1 colorless Myr artifact creature token to keep your artifact count flush. The result is a relentless cycle that drains your opponents to zero while padding your own life total indefinitely.
