Sin, Unending Cataclysm

Aura of Dominion

Blasting Station

Selvala, Heart of the Wilds

How it works

1. Cast Sin either from your hand or command zone by paying 5 plus commander tax if applicable.
2. As Sin enters, remove all counters from all artifacts, enchantments and creatures you control, putting twice that many +1/+1 counters on Sin.
3. When Sin enters, Blasting Station triggers, untapping Blasting Station.
4. Activate Selvala by paying and tapping it, adding at least plus an additional X equal to Sin's power minus 3.
5. Activate Aura of Dominion by paying 1 and tapping Sin, untapping Selvala.
6. Activate Blasting Station by tapping it and sacrificing Sin.
7. Choose to return Sin to the command zone from your graveyard.
8. When Sin dies, it triggers, putting its counters on Selvala.
9. Resolve the Blasting Station ability.
10. Repeat.
