Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight

Viscera Seer

Reputable Merchant

How it works

1. Activate Viscera Seer by sacrificing Reputable Merchant.
2. When Reputable Merchant dies, its innate ability and persist ability trigger.
3. Resolve the Reputable Merchant trigger, putting a +1/+1 counter on a creature you control.
4. Resolve the persist trigger, returning Reputable Merchant from your graveyard to the battlefield with a -1/-1 counter on it.
5. When Reputable Merchant enters, it triggers, putting a +1/+1 counter on it.
6. Resolve the Viscera Seer ability.
7. Repeat.
