Crystalline Crawler + Dancing from Dark to Dawn + Whitemane Lion

Crystalline Crawler

Dancing from Dark to Dawn

Whitemane Lion

How it works

1. Cast Whitemane Lion by paying its mana cost.
2. Dancing from Dark to Dawn's first ability triggers, putting two +1/+1 counters on Crystalline Crawler.
3. Resolve the Whitemane Lion spell. When it enters, it triggers, returning itself from the battlefield to your hand.
4. Activate Crystalline Crawler twice by removing two +1/+1 counters from it, adding 1.
5. Repeat.
