Removal interacts with mutate spells strangely If your opponent casts a creature for its mutate cost and you remove the creature it was mutating onto, the mutating creature spell doesn't fizzle
Once that spell or ability starts to resolve, however, and its controller chooses which permanents and players will get new counters, it's too late for anyone to respond
This set will be different from past Un-sets in one key way: it will contain many eternal tournament-legal cards
You pay all costs and follow all timing rules for artifact spells cast with the permission granted by Noctis's last ability
It turns out that Magic players love casting spells for free, even if free in this case is pay seven mana for an artifact and cross your fingers you overcome the randomness to get what you want. The silver lining, of course, is whatever spell youre copying from your graveyard gets to stay there on the chance youll copy it again, unlike many cards of this ilk that exile the spell following the resolution of the copy trigger, so if you can find a way to finesse only one legal target for the Crucibles trigger (perhaps by ensuring the top two cards of your library are lands with something like Senseis Divining Top), then youll get to copy the same thing over and over
