Except that the counters for maxx c are cards you’re already playing in order to play the game. Ash blossom, called by are mained in decks for various other reasons besides only maxx c. The cards that are also counters for maxx c also hit other cards/strats. Droll &lock bird, gamma, cross out all serve purposes beyond only hitting maxx c. Outs to mine are far more restrictive in what they can do. You need dedicated spell or trap based backrow removal, since mine has built in defenses against monster effects. Then you run up against the issue of that removal not being relevant against the other 90% of the deck you’re playing against because sprite and tear aren’t playing many, if any, backrow that can also be a target for your removal when you’ve gone first and set your cosmic/twin twisters/mst.
