MARK ROSEWATER WINS HE PRINTED A STICKER CARD THAT IS LEGACY PLAYABLe. LEGACY DECKS HAVE TO DEAL WITH HIS GIMMICK STICKER MECHANIC. HE DID IT HE KILLED MAGIC I'M SO HAPPY FOR HIM
so the thing about the new mechanics in Unfinity is they aren't very good. like most stuff, they aren't gonna make a splash in any eternal formats; maybe 1 or 2 cards will be good in pauper but with most of the rares as not-black-border or specifically built for commander they're not gonna make an impact in legacy.
HOWEVER.
they fucked up. and they fucked up with a card that everyone i know calls (no joke): MIND GOBLIN
lets talk about how this works
the funniest part of this is that it's of course only possible to do while supplies of sticker sheets last, since they're consumables.
nope! they technically count as counters, you can keep doing it so long as you have a replacement; and you can use a phone app or something to proxy the sticker sheets to prove which ones you're using.
is this wildly complicated and weird? yeah! almost like stickers are a baffling mechanic to have in constructed
