Druid's Call + Intruder Alarm + Lightning Prowess

Druid's Call

Intruder Alarm

Lightning Prowess

How it works

1. Activate the creature with Druid's Call and Lightning Prowess attached by tapping it, dealing 1 damage to itself.
2. Druid's Call triggers, creating a 1/1 Squirrel creature token.
3. When the Squirrel enters the battlefield, Intruder Alarm triggers, untapping all creatures.
4. Repeat.

By enchanting a single creature with both Druid's Call and Lightning Prowess, you transform it into a self-contained damage engine that triggers its own tapping ability. When that creature deals 1 damage to itself, Druid's Call rewards the self-inflicted wound by generating a 1/1 green Squirrel token. The arrival of that new token immediately rouses Intruder Alarm, whose global untap trigger snaps your entire board—including your targeted damage dealer—back upright and ready to fire again. This creates a closed loop where every tap fuels the creation of another Squirrel, letting you endlessly repeat the process for infinite creature tokens and infinite creature ETBs.
