Ghave, Guru of Spores + Young Wolf + Cryptic Trilobite

Ghave, Guru of Spores

Young Wolf

Cryptic Trilobite

How it works

1. Activate Cryptic Trilobite's first ability by removing a +1/+1 counter from it, adding CC that can only be spent to activate abilities.
2. Activate Ghave's second ability by paying 1 and sacrificing Young Wolf.
3. Young Wolf's undying ability triggers, returning it to the battlefield with a +1/+1 counter on it.
4. Resolve the Ghave ability, putting a +1/+1 counter on Cryptic Trilobite.
5. Activate Ghave's first ability by paying 1 and removing a +1/+1 counter from Young Wolf, creating a 1/1 Saproling creature token.
6. Repeat.
