The Watcher in the Water + Wylie Duke, Atiin Hero + Heart of Kiran + Blasting Station + Xenograft

The Watcher in the Water

Wylie Duke, Atiin Hero

Heart of Kiran

Blasting Station

Xenograft

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. When the Tentacle enters, Blasting Station triggers, untapping Blasting Station.
5. Resolve the Heart of Kiran ability, causing it to become a creature until end of turn.
6. Activate Blasting Station by tapping it and sacrificing the Tentacle.
7. When the Tentacle dies, The Watcher's second ability triggers, untapping Wylie Duke and putting a stun counter on up to one permanent.
8. Resolve the Blasting Station ability
9. Repeat.

This intricate loop turns Wylie Duke, Atiin Hero and Heart of Kiran into an opponent-turn engine fueled by Xenograft naming "Kraken," which ensures that The Watcher in the Water treats your tokens as Krakens ready to be untapped. When Wylie taps to crew the Heart, you draw a card that triggers The Watcher to spawn a Tentacle, which in turn untaps Blasting Station as it enters the battlefield. You then sacrifice that Tentacle to Blasting Station, triggering The Watcher to untap Wylie Duke so the entire cycle can begin anew.
