Crystalline Crawler + Dancing from Dark to Dawn + Kor Skyfisher

Crystalline Crawler

Dancing from Dark to Dawn

Kor Skyfisher

How it works

1. Cast Kor Skyfisher 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 Kor Skyfisher 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.
