Vigean Graftmage + Fertile Ground + Living Plane

Vigean Graftmage

Fertile Ground

Living Plane

How it works

1. Play the land that taps for multiple mana.
2. That land enters as a creature due to Living Plane, triggering Vigean Graftmage's Graft ability, allowing you to move a +1/+1 counter from Vigean Graftmage to that land.
3. Cast Fertile Ground by paying 1, attaching it to that land creature.
4. Activate that land by tapping it, adding at least two mana.
5. Fertile Ground triggers, adding at least one additional mana.
6. Activate Vigean Graftmage by paying 1, untapping the land creature.
7. Repeat.
