Havengul Lich + Grimgrin, Corpse-Born + Myr Moonvessel + Esika, God of the Tree // The Prismatic Bridge

Havengul Lich

Grimgrin, Corpse-Born

Myr Moonvessel

Esika, God of the Tree // The Prismatic Bridge

How it works

1. Activate Grimgrin by sacrificing Myr Moonvessel, untapping Grimgrin and putting a +1/+1 counter on it.
2. When Myr Moonvessel dies, it triggers, adding mana equal to its casting cost.
3. Activate Grimgrin's ability from Esika by tapping Grimgrin, adding one mana.
4. Activate Havengul Lich by paying 1, allowing you to cast Myr Moonvessel from your graveyard this turn.
5. Cast Myr Moonvessel from your graveyard by paying its casting cost.
6. Repeat.
