During an opponent's turn, activate Heart of Kiran by tapping Wylie Duke.
Wylie Duke triggers, causing you to draw a card and gain 1 life.
The Watcher's first ability triggers, creating a 1/1 Tentacle creature token.
Resolve the Heart of Kiran ability, causing it to become a creature until end of turn.
Activate Woe Strider by sacrificing the Tentacle.
When the Tentacle dies, The Watcher's second ability triggers, untapping Wylie Duke and putting a stun counter on up to one permanent.
Resolve the Woe Strider ability
Repeat.
This clever loop transforms an opponent's turn into an endless engine of draws and sacrifices, powered by the synergy between Arcane Adaptation and The Watcher in the Water. By setting your chosen creature type to Kraken with Arcane Adaptation, every creature you control—including the Goat from Woe Strider and the Tentacle tokens made by The Watcher in the Water—qualifies to satisfy The Watcher's untap trigger. You tap Wylie Duke to bypass the crew cost of Heart of Kiran, which conveniently triggers Wylie Duke to draw you a card and gain life. That card draw triggers The Watcher in the Water to spawn a Tentacle token, which you immediately sacrifice to Woe Strider. The death of that Tentacle untaps Wylie Duke via The Watcher's ability, letting you repeat the entire process to draw your entire deck and gain infinite life.
