If there's one thing I have learned since I got really good at this game, it is play for yourself. If people trash talk you then whatever MM them lol. If you wanna experiment then do it.Friendlies here seem to mean a lot more, so if I were to experiment and try new things, I'd probably have to endure trashtalk/taunts/whatever, unless I include the disclaimer of me not being completely serious. :\
But I like experimenting/being creative in friendlies. It's when the Toad and fsmash come out.
