Sin, Unending Cataclysm

Aura of Dominion

Blasting Station

Kami of Whispered Hopes

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 Aura of Dominion by paying 1 and tapping Sin, untapping Kami of Whispered Hopes.
5. Activate Blasting Station by tapping it and sacrificing Sin.
6. Choose to return Sin to the command zone from your graveyard.
7. When Sin dies, it triggers, putting its counters on Kami of Whispered Hopes.
8. Resolve the Blasting Station ability.
9. Activate Kami of Whispered Hopes by tapping it, adding an amount of or equal to its power.
10. Repeat.

This loop turns Sin, Unending Cataclysm into an explosive sacrifice engine by leveraging Kami of Whispered Hopes to exponentially scale its +1/+1 counters each time it returns from the command zone. As Sin enters, it strips counters from your permanents to fuel its size, while Blasting Station provides the repeatable sacrifice outlet and win condition that triggers every time Sin enters anew. Aura of Dominion allows you to tap Sin to untap Kami of Whispered Hopes, whose massive power—boosted by its own replacement effect and the counters transferred when Sin dies—generates more than enough colored mana to pay for the untap and recast costs.
