Disa the Restless + Mimic Vat + Grimgrin, Corpse-Born

Disa the Restless

Mimic Vat

Grimgrin, Corpse-Born

How it works

1. Activate Grimgrin by sacrificing a nontoken Lhurgoyf.
2. When the Lhurgoyf dies, Mimic Vat triggers, exiling the Lhurgoyf from your graveyard and returning the Lhurgoyf that was exiled to your graveyard.
3. Disa's first ability triggers, putting the Lhurgoyf from your graveyard onto the battlefield.
4. Resolve the Grimgrin ability, putting a +1/+1 counter on it.
5. Repeat.
