Simulator round 3, Spider woman essential node: I checked Rulk’s info and saw that he had 10 green AP, but required 12 to fire Hammer & the Anvil (I had a 5/3/5 Peggy to increase his AP costs). No problem, I’ll deny green until I can stun him.
I make my match, it switches to the AIs turn and Rulk immediately fires Hammer & Anvil, reducing Peggy’s health to 33% (5k out of 15k) which in turn nullifies her yellow passive.
Rulk should not have been able to fire green until Peggy was below 40% health. The result of Rulk’s green brought her below 40%, but the check should occur before he fires it, not after.
