Crystalline Crawler + Dancing from Dark to Dawn + Dream Stalker

Crystalline Crawler

Dancing from Dark to Dawn

Dream Stalker

How it works

1. Cast Dream Stalker 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 Dream Stalker 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.
