what do blue decks have to answer with mental misstep that we need 4 MM in the format, that blue decks couldn't handle with MM restricted?
What card must be kept in check with Mental Misstep that couldn't be kept in check before, besides A.Recall?
If I may, Chalice was restricted because it was viewed as keeping players from playing their cards in a format where you should be able to play your cards. Misstep is almost in the same boat, but worse, every blue deck runs it.
I'm not for restricting MM, just curious as to what your thoughts are on these points.
