I was about to say, RT claims he's garbage lol. But he does do a decent lucario.
I'd say that this MU has gotten a little better for sheik, and yes, camping is really stupid in this MU. Unfortunately, this isn't as bad as say, falco's camping, where we pretty much have to try to bleed ourselves out and string falco hardcore to get worth out of whatever hit we connect with, and then he has that stupid IAP to reset.
Anywho, lucario's have been getting wiser about punish options.
For whoever wanted to know, aura increases in damage, knockback, and shieldstun (aka the higher he is in damage, the more safe his moves become on block), and lucario fair is very good in this MU if used correctly. Ftilt has become the newer punisher for entry attempts, it's fsmash's little brother that compensates for it's poor killpower with twin, lingering hitboxes with range comparable to marth fair. Utilt will also be a big option in this MU, setting up sheik in the air where we want her more.
lucario usmash shouldn't be worried about too much, just don't make a move that commits much (thankfully lots of sheik's moves don't). FP doesn't CG anymore, people can mash out of it like a normal grab. However, it can still be used to string up stuff that lands about the same amount % wise, so still keep away from doing anything punishable.
You'll want to swan combo or whatever it's called, since lucario has a good answer for a ftilt-happy sheik. Dair alone does a lot of things to help lucario in this MU. I still think it's in our favor, I don't know about ratios though. Oh yeah, watch out for lucario setup moves and frame traps, he's got a lot of them.
What exactly is the frame data for needles? This may determine what camping measures people have lol.
I'll post more later probably.
