Plaguemaw Beast + Intruder Alarm + Scurry Oak

Plaguemaw Beast

Intruder Alarm

Scurry Oak

How it works

1. Activate Plaguemaw Beast by tapping it and sacrificing another creature, putting a +1/+1 counter on Scurry Oak.
2. Scurry Oak triggers, creating a 1/1 Squirrel creature token.
3. When the Squirrel enters the battlefield, Intruder Alarm triggers, untapping all creatures.
4. Repeat.

This clever loop centers around Plaguemaw Beast acting as the engine, turning a sacrificed creature into a proliferate trigger that feeds right back into your board state. Every time you activate it to sacrifice a creature, you add a +1/+1 counter to Scurry Oak, which conveniently triggers its ability to pump out a fresh 1/1 Squirrel token. That entering token is the key that unlocks Intruder Alarm's static ability, causing every creature on your side—including Plaguemaw Beast itself—to immediately untap and ready the whole chain for another repetition.
