ssb4 is really big on gimps and aerial play/counterplay. So to be more precise with what I said before, shulks play is aggression. you cant be complacent when they are shooting your face in. If its a secondary to make up shulks faults... well someone strong at range, consistent recovery and a faster ground game....maybe aerial.
Pits recovery is mad strong and arrows do gimp, his ground game is faster as well. Guardian orbitors give him additionalrojectile counter play.
Mario has a pretty great imo ground game.
Yoshi is very potent in the air. i like how all the other posters consider him too. reliable recovery, fast, nice grab range.
Marth is a faster version of shulk. if you want pure melee. I thought about it and ran off, Marth doesnt offer much difference.
sheik and greninja speak for themself.
imo charizard fits too, all that power but he isnt slow, strong grabs.
I mentioned R.O.B before because his range game is tight, he can reflect projectiles and punish rolls well. That and people said his recovery is nerfed but I think his-off ledge game is tight.
Strong recovery is getting important to me. Part of why im really feeling jump is that it makes them want to fight off-edge to kill secure and im coping more with that as i improve. jigglypuff is cool like that because her horizontal is ridic
