The 4 combo pieces

What must be in place

Dawnsire has ten or more charge counters on it.
Hellkite Charger cannot be blocked and killed by an opponent.

How to execute it

  1. Declare Hellkite Charger as an attacker, triggering it and Dawnsire.
  2. Resolve the Dawnsire trigger, attempting to deal 100 damage to Crystalline Crawler, which will result in 100 +1/+1 counters being placed on it instead due to Vigor.
  3. Holding priority, activate Crystalline Crawler's first ability seven times by removing seven +1/+1 counters from it, adding {5}{R}{R}.
  4. 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.
  5. Repeat each combat phase.
