The Watcher in the Water

Wylie Duke, Atiin Hero

Heart of Kiran

Umbral Collar Zealot

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 Umbral Collar Zealot 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 Umbral Collar Zealot ability, causing target player to mill cards equal to the Tentacle's power.
8. Repeat.

This engine transforms an ordinary vehicle into a perpetual motion machine by turning every moving part into fuel for your card draw. Maskwood Nexus does the heavy lifting behind the scenes, ensuring that the token it creates and the Tentacle tokens made by The Watcher in the Water all share every creature type, allowing them to cleanly satisfy any type-matching quirks while Umbral Collar Zealot sacrifices them away. Tapping Wylie Duke to crew Heart of Kiran triggers Wylie Duke's ability to draw you a card, which in turn prompts The Watcher in the Water to spawn a Tentacle. Feeding that Tentacle to Umbral Collar Zealot triggers The Watcher's second ability to untap Wylie Duke, leaving you ready to repeat the loop, gain life, and surveil your deck to your heart's content.
