Defiler of Faith + The Wind Crystal + Kor Skyfisher + Virulent Emissary

Defiler of Faith

The Wind Crystal

Kor Skyfisher

Virulent Emissary

How it works

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

This loop relies on a brilliant cost-reduction engine to cast Kor Skyfisher for free, turning every iteration into a cascade of value. With both Defiler of Faith and The Wind Crystal slashing the commander's generic and colored mana requirements down to zero, you can repeatedly cast the Skyfisher for just a couple of life points while the Defiler pumps out a fresh 1/1 Soldier token on each cast. As those tokens flood the board, Virulent Emissary transforms every entry into a steady stream of life, which The Wind Crystal happily doubles to keep your life total safe while you fuel the loop. Finally, Kor Skyfisher's own entry trigger forces it right back to your hand, resetting the process so you can endlessly repeat the cycle for infinite storm count, tokens, and lifegain.
