Squirrel Nest + Intruder Alarm + Nissa of Shadowed Boughs

Squirrel Nest

Intruder Alarm

Nissa of Shadowed Boughs

How it works

1. Animate the land that has Squirrel Nest attached using Nissa of Shadowed Boughs.
2. Activate the land with Squirrel Nest attached by tapping it, creating a 1/1 Squirrel creature token.
3. When the Squirrel enters, Intruder Alarm triggers, untapping all creatures.
4. Repeat from step 2.

This delightful loop transforms a humble patch of dirt into a relentless factory by combining Nissa of Shadowed Boughs, Squirrel Nest, and Intruder Alarm. Nissa provides the crucial catalyst by animating the enchanted land into a creature, allowing it to satisfy Intruder Alarm's arrival-triggered untap condition. Whenever that land-creature taps to create a 1/1 green Squirrel via Squirrel Nest, Intruder Alarm's static ability immediately triggers and untaps all creatures, including your animated land, leaving you ready to tap it all over again.
