Aaaaaa sorry for the late reply ;_;
Haha, I'm no good at competitive Smash either, especially not on the 3DS. The only Smash games where I've put sufficient time into competitive play are Melee and Project M, but I had to stop practicing them due to time constraints eheheh. I also play Smash 4 on the 3DS, but I hardly practiced at all, and I still haven't studied the metagame yet! Heck, I don't even know what 90% of the characters in Smash 4 do, haha. I just made sure to learn how to use Link. :P
