Kiri-Onna + Ugin's Conjurant + Ezzaroot Channeler + Bounteous Kirin + Defiler of Dreams

Kiri-Onna

Ugin's Conjurant

Ezzaroot Channeler

Bounteous Kirin

Defiler of Dreams

How it works

1. Cast Ugin's Conjurant, choosing to have X=2, but paying 0 due to Ezzaroot Channeler.
2. Bounteous Kirin and Kiri-Onna trigger.
3. Resolve the Bounteous Kirin trigger, causing you to gain two life.
4. Resolve the Kiri-Onna trigger, returning it to your hand from the battlefield.
5. Cast Kiri-Onna by paying two life due to Ezzaroot Channeler and Defiler of Dreams.
6. Defiler of Dreams triggers, causing you to draw a card.
7. When Kiri-Onna enters the battlefield, it triggers, returning Ugin's Conjurant to your hand from the battlefield.
8. Repeat.
9. Once you have drawn your library, you may cast Ugin's Conjurant with X equaling the amount of life you gained this turn to have it enter the battlefield with a large amount of +1/+1 counters, and to gain that much life due to Bounteous Kirin.

This intricate loop turns the synergy of ancient spirits and mystical dragons into an endless engine of card advantage and life. By tapping Ezzaroot Channeler, you gain the life needed to reduce Ugin's Conjurant's cost to zero, which in turn triggers Bounteous Kirin to sustain your life total while Kiri-Onna bounces itself back to your hand. As you recast Kiri-Onna, the health-payment discounts from Defiler of Dreams let you cycle through your deck endlessly thanks to its card-draw trigger, all while Kiri-Onna's entry trigger safely returns Ugin's Conjurant to hand to restart the cycle.
