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

Viscera Seer

Virtuous Variant

How it works

1. Activate Viscera Seer by sacrificing Virtuous Variant.
2. When Virtuous Variant dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When Virtuous Variant enters, it triggers, putting a +1/+1 counter on it.
4. Resolve the Viscera Seer ability.
5. Repeat.
