Cauldron Familiar + Witch's Oven + Intruder Alarm + March of the Machines + The Immortal Sun

Cauldron Familiar

Witch's Oven

Intruder Alarm

March of the Machines

The Immortal Sun

How it works

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

This delightfully looping dance hinges on turning your Kitchenware into living beings so they can talk to the machinery of the battlefield. With March of the Machines animating your artifacts into creatures, the Food token generated by sacrificing Cauldron Familiar to Witch's Oven immediately triggers Intruder Alarm, untapping all your creatures. You then feed that same Food back to recur the Familiar, whose re-entry triggers both its own life-draining ability and another refresh from Intruder Alarm. Meanwhile, The Immortal Sun quietly watches over the mayhem, pumping up your newly minted artifact creatures and discounting your spells while shutting down rival planeswalkers.
