Cauldron Familiar + Witch's Oven + Intruder Alarm + Ensoul Artifact

Cauldron Familiar

Witch's Oven

Intruder Alarm

Ensoul Artifact

How it works

1. Activate Witch's Oven by tapping it and sacrificing Cauldron Familiar, creating a Food artifact token.
2. Activate Cauldron Familiar by sacrificing a Food token, returning it from your graveyard to the battlefield.
3. When Cauldron Familar enters the battlefield, it and Intruder Alarm trigger.
4. Resolve the Cauldron Familiar trigger, causing each opponent to lose 1 life and you to gain 1 life.
5. Resolve the Intruder Alarm trigger, untapping all creatures.
6. Repeat.

This clever loop transforms a humble cat-and-oven routine into an infinite engine by leveraging Intruder Alarm to constantly untap your board whenever Cauldron Familiar enters the battlefield. To bridge the gap between Witch's Oven and the Alarm's creature-based triggers, Ensoul Artifact comes to the rescue by turning the Oven into a 5/5 creature, ensuring it untaps right alongside your looping cat. As you repeatedly sacrifice Cauldron Familiar to the animated Witch's Oven to bake a Food token and then immediately spend that Food to bring the Familiar right back, every single cycle drains your opponents dry while keeping your entire team primed and ready for action.
