How it works

1. Activate Skullclamp's equip ability by paying 0, attaching it to Crookshank Kobolds.
2. Crookshank Kobolds dies as a state-based action due to having zero toughness, triggering Enduring Renewal and Skullclamp.
3. Resolve the Enduring Renewal trigger, returning Crookshank Kobolds from your graveyard to your hand.
4. Resolve the Skullclamp trigger, causing you to draw two cards.
5. Cast Crookshank Kobolds by paying 0.
6. Repeat.
