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

Grimgrin, Corpse-Born

Visionary Augmenter

How it works

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