Defiler of Faith + Oketra's Monument + Whitemane Lion + Haliya, Guided by Light

Defiler of Faith

Oketra's Monument

Whitemane Lion

Haliya, Guided by Light

How it works

1. Cast Whitemane Lion by paying 0 and 2 life due to Defiler of Faith and Oketra's Monument.
2. Defiler of Faith and Oketra's Monument trigger.
3. Resolve the Defiler of Faith trigger, creating a 1/1 Soldier creature token.
4. When the Soldier enters, Haliya triggers, causing you to gain life.
5. Resolve the Oketra's Monument trigger, creating a 1/1 Warrior creature token.
6. When the Warrior enters, Haliya triggers, causing you to gain life.
7. Resolve Whitemane Lion. When it enters, it and Haliya trigger.
8. Resolve the Whitemane Lion trigger, returning it from the battlefield to your hand.
9. Resolve the Haliya trigger, causing you to gain life.
10. Repeat.

This elegant loop relies on stacking cost reductions from Defiler of Faith and Oketra's Monument to cast Whitemane Lion for zero mana, paying a small amount of life instead. Every time the Lion enters the battlefield, its own trigger bounces it right back to your hand so you can cast it again, while the Defiler of Faith and Oketra's Monument pump out an endless army of tokens. Meanwhile, Haliya, Guided by Light happily watches the revolving door of creatures, turning every single entry into a steady stream of life and easily crossing the threshold to draw you a card during your end step.
