The Watcher in the Water + Wylie Duke, Atiin Hero + Heart of Kiran + Goblin Bombardment + Rukarumel, Biologist

The Watcher in the Water

Wylie Duke, Atiin Hero

Heart of Kiran

Goblin Bombardment

Rukarumel, Biologist

How it works

1. During an opponent's turn, activate Heart of Kiran by tapping Wylie Duke.
2. Wylie Duke triggers, causing you to draw a card and gain 1 life.
3. The Watcher's first ability triggers, creating a 1/1 Tentacle creature token.
4. Resolve the Heart of Kiran ability, causing it to become a creature until end of turn.
5. Activate Goblin Bombardment by sacrificing the Tentacle.
6. When the Tentacle dies, The Watcher's second ability triggers, untapping Wylie Duke and putting a stun counter on up to one permanent.
7. Resolve the Goblin Bombardment ability
8. Repeat.

This intricate loop transforms a single card draw into an engine of near-infinite damage, lifegain, and card draw during your opponent's turn. It all hinges on Rukarumel, Biologist establishing a shared identity, though the heavy lifting is done by Wylie Duke, Atiin Hero crewing Heart of Kiran to tap itself, which triggers both life and a card draw. That draw wakes up The Watcher in the Water to spawn a Tentacle token, which you promptly feed to Goblin Bombardment. When the Tentacle dies, The Watcher in the Water’s second ability untaps Wylie Duke, readying the whole cycle to repeat endlessly.
