Bishop of Wings + Goblin Bombardment + Xenograft

Bishop of Wings

Goblin Bombardment

Xenograft

How it works

1. Activate Goblin Bombardment by sacrificing another creature.
2. When the creature dies, Bishop of Wings' second ability triggers, creating a 1/1 Spirit creature token.
3. When the Spirit token enters the battlefield as an Angel due to Xenograft, Bishop of Wings' first ability triggers, causing you to gain 4 life.
4. Resolve the Goblin Bombardment ability.
5. Repeat.

This loop relies on Xenograft to fundamentally rewrite the rules of your battlefield, declaring every creature you control to be an Angel in addition to its other types. With that foundation set, you can sacrifice a Spirit token to Goblin Bombardment to deal a point of damage. That death immediately triggers Bishop of Wings to create a replacement 1/1 Spirit token, which then enters the battlefield as an Angel thanks to Xenograft, triggering Bishop of Wings' first ability to restore 4 life to you. By feeding the resulting Spirit right back into Goblin Bombardment, you turn a closed loop of life and death into an unstoppable cycle of infinite damage and lifegain.
