Cauldron Familiar + Witch's Oven + Intruder Alarm + Karn, Silver Golem

Cauldron Familiar

Witch's Oven

Intruder Alarm

Karn, Silver Golem

How it works

1. Activate Karn by paying 1, causing Witch's Oven to become an artifact creature until end of turn.
2. Activate Witch's Oven by tapping it and sacrificing Cauldron Familiar, creating a Food token.
3. Activate Cauldron Familiar by sacrificing a Food token, returning it from your graveyard to the battlefield.
4. Cauldron Familar enters the battlefield, triggering Intruder Alarm, untapping all creatures.
5. Repeat from step 2.

This clever loop uses Karn, Silver Golem to animate Witch's Oven into an artifact creature, allowing it to be sacrificed to fuel Cauldron Familiar and vice-versa. Every time the cat returns to the battlefield, Intruder Alarm triggers to untap all creatures, resetting your newly animated Witch's Oven so the cycle can start anew. This perpetual mechanical dance drains your opponents to zero while churning out infinite sacrifice and enter-the-battlefield triggers.
