The Watcher in the Water + Wylie Duke, Atiin Hero + Heart of Kiran + Thermopod + Maskwood Nexus

The Watcher in the Water

Wylie Duke, Atiin Hero

Heart of Kiran

Thermopod

Maskwood Nexus

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 Thermopod 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. Repeat.

This fascinating engine relies on Maskwood Nexus to turn all your creatures into every creature type, ensuring that the token created by The Watcher in the Water is a Kraken capable of being untapped by its own death trigger. By crewing Heart of Kiran with Wylie Duke, you draw a card during your opponent's turn, which in turn commands The Watcher to spawn a Tentacle. You then feed that creature to Thermopod for red mana, triggering the Watcher once more to untap Wylie Duke so the whole loop can begin anew while steadily netting life and resources.
