This masterclass in bending reality starts by casting The Legend of Kuruk // Avatar Kuruk, whose backside brings a massive *Exhaust* waterbend ability to the table. Because Marvin, Murderous Mimic copies all activated abilities of your other creatures without sharing a name, it eagerly mirrors that formidable mana-and-tap payment requirement, letting you take an extra turn. Finally, Thassa, Deep-Dwelling steps in at your end step to exile and blink Marvin, resetting its once-per-game *Exhaust* restriction so you can repeat the whole sequence every turn for infinite extra turns.
