Defiler of Faith + Trostani, Selesnya's Voice + Kor Skyfisher + Grand Arbiter Augustin IV

Defiler of Faith

Trostani, Selesnya's Voice

Kor Skyfisher

Grand Arbiter Augustin IV

How it works

1. Cast Kor Skyfisher by paying 0 and 2 life due to Defiler of Faith and Grand Arbiter Augustin IV.
2. Defiler of Faith triggers, creating a 1/1 Soldier creature token.
3. When the Soldier enters, Trostani triggers, causing you to gain life.
4. Resolve Kor Skyfisher. When it enters, it and Trostani trigger.
5. Resolve the Kor Skyfisher trigger, returning it from the battlefield to your hand.
6. Resolve the Trostani trigger, causing you to gain life.
7. Repeat.

This elegant loop uses Grand Arbiter Augustin IV alongside Defiler of Faith to completely eliminate the mana cost of Kor Skyfisher, allowing you to cast it over and over for just a bit of life. Every time the Skyfisher enters the battlefield, its own drawback forces it right back to your hand, while Defiler of Faith's triggered ability rewards each cast by churning out a fresh 1/1 Soldier token. Meanwhile, Trostani, Selesnya's Voice watches over the proceedings, turning every single Soldier entering the battlefield into a steady stream of lifegain to offset what you paid to the Defiler.
