Cauldron Familiar + Witch's Oven + Intruder Alarm + March of the Machines + Forsaken Monument

Cauldron Familiar

Witch's Oven

Intruder Alarm

March of the Machines

Forsaken Monument

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 clever loop turns a modest kitchen witchery into a relentless engine of life drain. With March of the Machines animating every noncreature artifact into a creature, your newly baked Food token from Witch's Oven enters as a creature, immediately satisfying Intruder Alarm to untap everything in play. You then feed that same Food right back into Cauldron Familiar's ability to recur the cat from your graveyard, draining your opponents while triggering the alarm all over again. Meanwhile, Forsaken Monument quietly supercharges your mana production and pads your life total even further simply by existing on the battlefield.
