This crafty engine hinges on Shipwreck Dowser's ability to pull Cloudshift right back out of the graveyard every single time it blinks back onto the battlefield.

By cracking that Treasure for the exact white mana needed to recast the spell, we loop the whole process indefinitely, fueling an endless cascade of magecraft triggers and artifact movements.
