Chulane triggers, causing you to draw a card and put Orzhov Basilica from your hand onto the battlefield.
Orzhov Basilica enters the battlefield, triggering itself and Tireless Provisioner.
Resolve the Tireless Provisioner trigger, creating a Treasure token.
Resolve the Orzhov Basilica trigger, returning it from the battlefield to your hand.
Shrieking Drake enters the battlefield, returning itself from the battlefield to your hand.
Activate the Treasure token by tapping and sacrificing it, adding .
Repeat.
This clever loop is orchestrated by Chulane, Teller of Tales, whose presence turns every creature cast into a cantrip and an opportunity to accelerate your land drops. By dropping Shrieking Drake, you trigger Chulane to pull Orzhov Basilica straight from your hand onto the battlefield without spending mana. The Basilica's own entry triggers its return-to-hand clause alongside Tireless Provisioner's landfall ability, which conveniently spawns a Treasure token to help pay for the Drake's next casting. As Shrieking Drake bounces itself back to your hand, you simply sacrifice the Treasure generated by Tireless Provisioner to recast the Drake, sustaining an engine that endlessly draws your deck, pumps your storm count, and triggers any number of enters-the-battlefield effects.
