Intruder Alarm + Stonybrook Schoolmaster + Fatestitcher

Intruder Alarm

Stonybrook Schoolmaster

Fatestitcher

How it works

1. Activate Fatestitcher by tapping it, tapping Stonybrook Schoolmaster.
2. Stonybrook Schoolmaster triggers, creating a 1/1 Merfolk Wizard creature token.
3. When the Merfolk Wizard enters the battlefield, Intruder Alarm triggers, untapping all creatures.
4. Repeat.

This elegant loop turns a simple tap into a cascade of endless reinforcements by bridging active manipulation with passive triggers. When you use Fatestitcher's tap ability to target Stonybrook Schoolmaster, the Schoolmaster’s ability triggers to spawn a 1/1 blue Merfolk Wizard token. That new arrival immediately awakens Intruder Alarm, whose static enchantment ability triggers to untap all creatures on the board—including both Fatestitcher and the Schoolmaster—readying the entire pair to repeat the cycle infinitely.
