Cultivator of Blades

How it works

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