Felhide Spiritbinder

Intruder Alarm

Burning-Tree Emissary

How it works

1. Activate Felhide Spiritbinder by tapping it, dealing 1 damage to any target.
2. Cast Burning-Tree Emissary by paying R/GR/G.
3. When Burning-Tree Emissary enters the battlefield, it and Intruder Alarm trigger.
4. Resolve the Burning-Tree Emissary trigger, adding .
5. Resolve the Intruder Alarm trigger, untapping all creatures.
6. Felhide Spiritbinder triggers, holding priority, activate it by tapping it, dealing 1 damage to any target.
7. Resolve the Felhide Spiritbinder trigger, causing you to pay 1 to create a token copy of Burning-Tree Emissary with haste.
8. Repeat from step 3.

This ingenious loop transforms a simple inspired trigger into an infinite engine by leveraging Intruder Alarm's global untap whenever a creature enters the battlefield. By enchanting Felhide Spiritbinder with Arcane Teachings, you gain the crucial ability to tap it for damage to cleanly trigger its untap-based copying ability without needing outside combat. As you continually cast Burning-Tree Emissary, its entry triggers the Alarm to untap your minotaur, letting you tap it again in response to pay the copy cost and flood the board with haste-granting copies while generating a surplus of mana.
