The Watcher in the Water + Wylie Duke, Atiin Hero + Heart of Kiran + Shilgengar, Sire of Famine + Amorphous Axe

The Watcher in the Water

Wylie Duke, Atiin Hero

Heart of Kiran

Shilgengar, Sire of Famine

Amorphous Axe

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 Shilgengar 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 Shilgengar ability
8. Repeat.

This ingenious loop turns Wylie Duke, Atiin Hero and Heart of Kiran into a self-sustaining engine during your opponent's turn by tapping the Hero to crew the Vehicle without paying mana. Each time Wylie Duke taps, its ability draws you a card which immediately triggers The Watcher in the Water to spawn a 1/1 blue Tentacle creature token. Amorphous Axe can quietly ensure creature type synergy if needed, while Shilgengar, Sire of Famine stands ready to sacrifice that freshly made Tentacle for a Blood token. When the Tentacle dies, The Watcher in the Water's second ability cleverly untaps Wylie Duke, readying it to repeat the process for near-infinite card draw, lifegain, and Blood tokens.
