Crystalline Crawler + Dancing from Dark to Dawn + Spider-Byte, Web Warden

Crystalline Crawler

Dancing from Dark to Dawn

Spider-Byte, Web Warden

How it works

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