This ingenious loop turns a simple vehicle into an engine of continuous value by letting Wylie Duke, Atiin Hero crew Heart of Kiran to tap itself, which in turn draws you a card during your opponent's turn. That draw immediately triggers The Watcher in the Water to spawn a 1/1 Tentacle token, providing fresh fodder for Woe Strider to sacrifice. When the Tentacle dies, The Watcher in the Water's second ability triggers to untap Wylie Duke, readying the hero to crew the vehicle again while Psychic Paper and the rest of the board stand by to facilitate this wondrous transformation.
