Blasting Station + Wormfang Drake + Metamorphosis Fanatic

Blasting Station

Wormfang Drake

Metamorphosis Fanatic

How it works

1. Cast Wormfang Drake by paying its mana cost.
2. When Wormfang Drake enters, its first ability and Blasting Station trigger.
3. Resolve the Wormfang Drake trigger, exiling Metamorphosis Fanatic.
4. Resolve the Blasting Station trigger, untapping it.
5. Activate Blasting Station by tapping it and sacrificing Wormfang Drake.
6. When Wormfang Drake dies, its second ability triggers, returning Metamorphosis Fanatic from exile to the battlefield.
7. When Metamorphosis Fanatic enters, it and Blasting Station trigger.
8. Resolve the Blasting Station trigger, untapping it.
9. Resolve the Metamorphosis Fanatic trigger, returning Wormfang Drake from your graveyard to the battlefield.
10. Repeat steps 2 through 4 one additional time.
11. Resolve the Blasting Station ability from step 5.
12. Repeat from step 5.

This loop dances back and forth between the graveyard and the battlefield by exploiting the delayed triggers of Wormfang Drake and Metamorphosis Fanatic. When Wormfang Drake enters, it exiles Metamorphosis Fanatic, but sacrificing the Drake to Blasting Station instantly returns the Fanatic to play. Metamorphosis Fanatic then triggers to pull the Drake right back from the graveyard, re-priming the cycle while Blasting Station untaps itself to repeatedly turn those entry and death triggers into infinite damage to any target.
