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

The Watcher in the Water

Wylie Duke, Atiin Hero

Heart of Kiran

Carrion Feeder

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 Carrion Feeder 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 Carrion Feeder ability
8. Repeat.

This clever loop transforms Wylie Duke, Atiin Hero and Heart of Kiran into a self-sustaining engine by utilizing Wylie Duke's ability to crew the Vehicle and tap itself for card draw during an opponent's turn. Rukarumel, Biologist quietly ensures all your nontoken creatures share the chosen type, though the real magic happens when The Watcher in the Water responds to that card draw by churning out a Tentacle token. You then feed that token to Carrion Feeder, whose sacrifice triggers The Watcher's second ability to untap Wylie Duke—resetting the entire process so you can loop it all over again for infinite card draw and growth.
