3. Activate Aura of Dominion by paying 1 and tapping Sin, untapping Kami of Whispered Hopes.
4. Activate Altar of Dementia by sacrificing Sin.
5. Choose to return Sin to the command zone from your graveyard.
6. When Sin dies, it triggers, putting its counters on Kami of Whispered Hopes.
7. Resolve the Altar of Dementia ability.
