Pit is a lot like Peach IMO learn SDI for this MU it shuts down a stupid number of his options Uair becomes less annoying espically when hes planking Fsmash becomes way harder to kill with. and never try to camp him Pits camping game is ridiculous he can literally choose to almost never approach you. if the pit is half decent crouching becomes a lot less viable to I use pit as a secondary and il just aim the arrows down when their over top of the enemy which will easily nail you crouching so yeah make sure your PSing arrows walking PS is your friend. im pretty sure he can screw you royally on your recovery with the mirror shield with Pit your pretty safe around the D3 hammer Filt range i find dont be afraid to kinda weave in and out of him. also note that pit is a lot like pikachu with pretty sad Zoneing tools or at least range on his Zoning tools at least when compared to a character like marth who has alot more walling abilities. you really have to use your speed in this MU and out play him at CQC and apply pressure when you can. IMO pit has a advantage in the neutral against pikachu but if we get our paws on him he doesnt have a very good time. And tilts are your friend to D tilt for instance has good range in this MU. Be very careful of his WOI or his Up B cause when he activates it if he chooses to fast fall he drops stupid fast allowing for great surprising kills and really opens up his ability to land when your trying to juggle and watch out for Dairs and F/Bair espically WOI FFed ones. I cant remember off the top of my head cause its late but IIRC he can reflect skull bash to allowing an easy edge guard and he can also WOI cancel the ledge allowing for stupid fast ledge regrabs so be careful challenging him on the ledge, and same with when your recovering, be wary that if he predicts your obvious QA into ledge and hes around the ledge your probably dead cause that move has a silly sized ledge magnet on it to. so be alert and understand the weird properties of the moves so he cant surprise kill you.
