Crystalline Crawler + Dancing from Dark to Dawn + Hoverguard Sweepers

Crystalline Crawler

Dancing from Dark to Dawn

Hoverguard Sweepers

How it works

1. Cast Hoverguard Sweepers by paying its mana cost.
2. Dancing from Dark to Dawn's first ability triggers, putting eight +1/+1 counters on Crystalline Crawler.
3. Resolve the Hoverguard Sweepers spell. When it enters, it triggers, returning itself from the battlefield to your hand.
4. Activate Crystalline Crawler eight times by removing eight +1/+1 counters from it, adding 6.
5. Repeat.
