The 3 combo pieces

What must be in place

Crystalline Crawler has at least five +1/+1 counters on it.
Crystalline Crawler does not have summoning sickness and cannot be blocked and killed by an opponent.

How to execute it

  1. Declare Crystalline Crawler as an attacker.
  2. Byrke's second ability triggers, doubling the number of +1/+1 counters on Crystalline Crawler.
  3. Move to your postcombat main phase.
  4. Activate Crystalline Crawler's first ability five times by removing five +1/+1 counters from it, adding {3}{R}{R}.
  5. Activate Aggravated Assault by paying {3}{R}{R}, causing you to untap all creatures you control and to get an additional combat phase after this one.
  6. Repeat.
  7. If Crystalline Crawler has at least six +1/+1 counters on it, this combo nets infinite +1/+1 counter doubling.
