barracius asked:

Surgeon ~~General~~ Commander from Unsanctioned says "Whenever you enchant, augment, or mutate a creature you control." Now we know what two of those are, but not mutate. Is that a joke similar to Steamflogger Boss's contraption assembly? Does combining creatures with Grusilda count as mutating?

Mutate is a keyword you all haven’t seen yet. And fear not, we’ve learned from Steamflogger Boss to not make-up mechanics we have no intent of making.
