Ghave, Guru of Spores + Earthcraft + Sigil Captain

Ghave, Guru of Spores

Earthcraft

Sigil Captain

How it works

1. Activate a basic land by tapping it, adding 1.
2. Activate Ghave's first ability by paying 1 and removing a +1/+1 counter from a creature you control, creating a 1/1 Saproling creature token.
3. When the Saproling enters the battlefield, Sigil Captain triggers, putting two +1/+1 counters on the Saproling.
4. Activate Earthcraft by tapping the Saproling token, untapping a basic land.
5. Repeat.
