Vigean Graftmage + Nature's Revolt + Groundchuck & Dirtbag

Vigean Graftmage

Nature's Revolt

Groundchuck & Dirtbag

How it works

1. Play the land that taps for multiple mana.
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 at least two mana.
4. Groundchuck & Dirtbag triggers, adding at least one additional mana.
5. Activate Vigean Graftmage by paying 1, untapping the land creature.
6. Repeat.
