How it works
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, copying another nonlegendary Saga you control and putting two to three lore counters on it.
The Saga tokens first through fourth chapter abilities trigger, as applicable. Resolve all triggers, and sacrifice the Saga token upon resolving the final trigger.
When the Saga token leaves the battlefield, Resourceful Defense triggers, moving the lore counters from the Saga token onto Esper Terra.
Esper Terra's second, third and fourth chapter abilities trigger.
Resolve the second and third chapter abilities.
Resolve the fourth chapter ability, adding and then exiling Esper Terra and returning it to the battlefield as Terra, Magical Adept.
Resourceful Defense and Terra, Magical Adept trigger.
Resolve the Resourceful Defense trigger, moving all counters from Esper Terra onto any other permanent
Resolve the Terra, Magical Adept trigger, causing you to mill five cards and return up to one enchantment card from among them from your graveyard to your hand.
Repeat.
This intricate loop is masterminded by Esper Terra's ability to recursively transform back and forth while spinning up exponential value. You start by using Terra, Magical Adept's Trance ability to flip into its Saga back face, which then leans on Resourceful Defense to catch and preserve lore counters as tokens leave the battlefield, feeding them right back onto the Saga to accelerate its progression. Along the way, Frostcliff Siege can sit on the board providing steady card draw or offensive pressure, while the Saga tokens themselves copy nonlegendary enchantments to multiply your battlefield presence. When Esper Terra reaches its final chapter, it yields a massive influx of all five colors of mana before resetting to its front face, letting you repeat the whole cycle for infinite enters-the-battlefield triggers, self-mill, and mana.
