This intricate loop turns a vehicle into an engine of continuous card-drawing power by weaving together a clever tribal identity and a sacrifice outlet. Arcane Adaptation is the hidden glue of the operation, ensuring that the tokens created by The Watcher in the Water also count as Krakens so they can legally untap Wylie Duke—who conveniently taps to crew Heart of Kiran without needing to swing. Every time Wylie Duke taps, you draw a card to trigger The Watcher in the Water, creating a Tentacle token that you promptly feed to Viscera Seer. When that sacrifice happens, The Watcher in the Water triggers its second ability to untap Wylie Duke, letting you immediately start the cycle all over again for infinite card draw, life, and death triggers.
