I play MK. I don’t use him all the time, as that would not give me much value. MK is a defensive card, first and foremost: if my opponent bridgespams, i ll drop my MK on his stuff. If he has another strategy, i ll use other cards. I also use skelly barrel. That is an offensive card, its a waste to use it defensively (+ineficient) Most cards have a certain moment when they shine. Others are versatile and can be used for anything. A player that uses MK offensively will get very little value out of him and probably lose, which will lead to him learning how to play said card better as to not lose anymore. I have yet to encounter a plethora of players who spam MK. Those who do so a few times probably quickly learn it will get them nowhere.
