Passives aren’t supposed to fire again after making a match-5, at least I have never experienced them. Galactus apparently can do this. Watching him go from 0 AP to 30 in a single turn because he got a lucky cascade that turned into a match-5 is decidedly not fun. I’ve seen him do this twice now.
Wow…I haven’t seen this, but now I’m terrified. As if he wasn’t already stupid hard.
