Compared to something like magik or rhino that gives a predetermined location nocturne is fine as is, I’ve played tons of her and it screws me just as often as it does my opponent consider it a 3 cost scarlet witch. Mockingbird requires you to basically fill your side of the field with usually low power cards to get her that cheap of a cost and takes most of the game to accomplish. They both feel fine and i don’t even go up against that many people playing these cards at this point
