The Watcher in the Water + Wylie Duke, Atiin Hero + Heart of Kiran + Bloodflow Connoisseur + Leyline of Transformation

The Watcher in the Water

Wylie Duke, Atiin Hero

Heart of Kiran

Bloodflow Connoisseur

Leyline of Transformation

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 Bloodflow Connoisseur 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 Bloodflow Connoisseur ability
8. Repeat.

This intricate engine turns your opponent's turn into an endless loop by leveraging Leyline of Transformation to make Wylie Duke, Atiin Hero—and every other creature you control—count as a Kraken to satisfy The Watcher in the Water's untap condition. You begin by tapping Wylie Duke to crew Heart of Kiran without paying mana; this action draws you a card, which immediately prompts The Watcher in the Water to spawn a 1/1 Tentacle. You then feed that Tentacle to Bloodflow Connoisseur, whose sacrifice triggers The Watcher in the Water's second ability to untap Wylie Duke and ready him to be tapped by Heart of Kiran all over again.
