This elegant loop leverages Chulane, Teller of Tales as your command center, rewarding every creature cast with a card drawn and a land dropped straight onto the battlefield. By casting Shrieking Drake, you trigger Chulane to sneak Dimir Aqueduct into play; the land's own bounce trigger then returns it to your hand while Tireless Provisioner churns out a steady stream of Treasure tokens via landfall. Sacrificing that freshly minted Treasure supplies the exact blue mana needed to replay the Drake, which conveniently bounces itself back to your hand to restart the cycle. Because Dimir Aqueduct continually bounces itself, you never actually run out of lands to trigger your Provisioner, letting you draw your entire deck and rack up boundless triggers at will.
