The Watcher in the Water + Wylie Duke, Atiin Hero + Heart of Kiran + Altar of Dementia + Arcane Adaptation

The Watcher in the Water

Wylie Duke, Atiin Hero

Heart of Kiran

Altar of Dementia

Arcane Adaptation

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 Altar of Dementia 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 Altar of Dementia ability
8. Repeat.

This clever loop transforms Wylie Duke, Atiin Hero into a tireless engine by tapping him to crew Heart of Kiran on an opponent's turn, which triggers Wylie Duke to draw a card and gain you life. Thanks to Arcane Adaptation naming "Kraken" and "Tentacle," The Watcher in the Water treats your creatures accordingly, spawning a Tentacle token from that drawn card and utilizing its own dying trigger to untap Wylie Duke when you sacrifice the token to Altar of Dementia. Because Heart of Kiran's crew ability can be activated repeatedly at instant speed, you can cycle this sequence to mill your entire library, draw infinite cards, and gain massive amounts of life.
