Sigarda's Summons + Bishop of Wings + Cathars' Crusade + Blasting Station

Sigarda's Summons

Bishop of Wings

Cathars' Crusade

Blasting Station

How it works

1. Activate Blasting Station by sacrificing an Angel.
2. Bishop of Wings triggers, creating a 1/1 Spirit creature token.
3. The Spirit enters the battlefield, triggering Cathars' Crusade and Blasting Station.
4. Resolve the Cathars' Crusade trigger, putting a +1/+1 counter on each creature you control.
5. The Spirit token becomes a 4/4 Spirit Angel due to having a +1/+1 counter on it.
6. Resolve the Blasting Station trigger from step 3, untapping itself.
7. Resolve Blasting Station's remaining ability, dealing 1 damage to any target.
8. Activate Blasting Station by tapping it and sacrificing the Spirit token.
9. Repeat from step 2.
