How it works

2. When Furystoke Giant dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When Furystoke Giant enters, Stalwart Successor triggers, putting a +1/+1 counter on Furystoke Giant
4. Resolve the Shilgengar ability.
5. Repeat.
