Steps
- At the beginning of your combat phase, Maester Seymour triggers, putting at least seven +1/+1 counters on Crystalline Crawler.
- Declare Hellkite Charger as an attacker, triggering its ability.
- Holding priority, activate Crystalline Crawler's first ability seven times by removing seven +1/+1 counters from it, adding {5}{R}{R}.
- Resolve the Hellkite Charger trigger, causing you to pay {5}{R}{R} to untap all attacking creatures you control and to get an additional combat phase after this one.
- Repeat.
