Vigean Graftmage + Nature's Revolt + Overgrowth

Vigean Graftmage

Nature's Revolt

Overgrowth

How it works

1. Play any land card.
2. That land enters as a creature due to Nature's Revolt, triggering Vigean Graftmage's Graft ability, allowing you to move a +1/+1 counter from Vigean Graftmage to that land.
3. Activate that land by tapping it, adding one mana.
4. Overgrowth triggers, adding at least two additional mana.
5. Activate Vigean Graftmage by paying 1, untapping the land creature.
6. Repeat.
