Glint-Sleeve Artisan

How it works

2. When Glint-Sleeve Artisan dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When Glint-Sleeve Artisan enters, its fabricate ability triggers, putting a +1/+1 counter on it.
4. Resolve the Spawning Pit ability.
5. Repeat.
