Activate Terra, Magical Adept by paying 4 and tapping it, exiling it and returning it to the battlefield as Esper Terra.
When Esper Terra enters the battlefield, its first chapter ability triggers, creating a token copy of Mesmerizing Dose.
When the Mesmerizing Dose token enters the battlefield, it triggers, putting a lore counter on Esper Terra.
Repeat from step 2 two additional times, from Esper Terra's second and third chapter abilities triggering.
Esper Terra's fourth chapter ability triggers, causing you to add , and then exile Esper Terra and return it to the battlefield as Terra, Magical Adept.
When Terra, Magical Adept enters the battlefield, it triggers, causing you to mill five cards and return up to one enchantment card from among them from your graveyard to your hand.
Repeat.
This dazzling loop relies on an infinite recursive engine fueled by Esper Terra's ability to constantly copy and re-trigger enchantments. By utilizing the token-copying chapters of Esper Terra alongside a looping cycle that resets back into Terra, Magical Adept, every new iteration lets Mesmerizing Dose re-enter to proliferate counters and advance the Saga. Kratos, God of War rounds out the battlefield with haste and damage, though the true engine here is the perpetual motion machine between the transformative Saga and the cloned Auras.
