I play every now and again. I don't use Lucario too often since I'm not good with him and don't know how to improve, but I do use him on occasion. I main Kirby and choose Diddy as a secondary. I also play with several others when doing friendlies.
You might see it as lame, but I tend to play the "boring" way (meaning three/four stock, no items), but I sometimes go with items if it's a four-player free for all.
