Chulane triggers, causing you to draw a card and put Dimir Aqueduct from your hand onto the battlefield.
Dimir Aqueduct enters the battlefield, triggering itself and Lotus Cobra.
Resolve the Lotus Cobra trigger, adding .
Resolve the Dimir Aqueduct trigger, returning it from the battlefield to your hand.
Shrieking Drake enters the battlefield, returning itself from the battlefield to your hand.
Repeat.
This clever loop turns the self-bouncing nature of Shrieking Drake into a perpetual motion machine, fueled from the command zone by Chulane, Teller of Tales to draw your entire deck and drop every land from your hand. Lotus Cobra acts as the critical mana engine, converting each land drop into the exact blue mana needed to recast the Drake over and over. Meanwhile, Dimir Aqueduct serves as the anchor of the loop; its bounce-on-entry ability continuously resets itself back to your hand so Chulane can cheat it right back into play for endless landfall triggers.
