This what is gonna happen next:
If you have been in DL for a while you probably have noticed how when a deck is hit hard by the banlist the deck moves to a balance build, pretend everything is fine, click bait video on yt "x deck is not dead", etc... at the end the deck dissapears of the map or barely hangs in there for a few months.
That is what is gonna happen to karakuri, witchcrafter (unless tea drops something good), any deck that wants neos fusion and any non archetypal fusion deck with keeper.
Oh come on. Sure, karakuri having their main synchro player being set to 2 is gonna hurt a bit but so what? If you like a deck you're going to find a way to make it work. If you look at a deck and go "Not viable, not playing" then what's even the point of playing? Just run simulations of your copy of the top deck against everyone else's, it'll save you time and get the same results
yep I remember that happening to heroes then they got powercrept and became the most pathetic excuse of a deck I had ever seen with 3 drill dark, 2 celestial, 2 deciders and tons of floodgate, canadia, mirror, disruption, etc....then they got support many month later.
The difference between rich meta slaves and poor meta slaves. Rich meta slaves will just copypaste any post-banlist tier 1 deck. Poor meta slaves will try their best to make the old nerfed deck playable because it is the only deck they have and they need months of saving gems to copy new meta deck.
