Level 9 cpus just read your inputs, so they aren't that great to train with. If you want to train with bots use a level 7. You can also just use training mode to learn characters and whatnot. I would say play for glory but it's not very good, use Smash ladder and you're bound to find some decent players. Just playing against others helps loads.Does fighting level 9 bots help you train, or is there a better method to help in the competition? I am extremely bad so I want to know how to get better.
Oh yeah and watch this youtuber's videos, he shows off some very useful stuff.
