Also, Link & Bowser, what do you guys think about those matchups? There's a guy in our region who mains both that I haven't played yet. I know ducking grab and boomerang is important for Link, but that's about the extent of my knowledge
I first learned to play PM with bowser and my roomate is a bowser main a, and while he is nowhere near competitive material, I can give some insight into the matchup. Basically bowser is super combo food, as long as you dont get too gready, in which case youll probably be eating a super armor nair or worse, a down b from right underneath the blastzone. You have to learn when you just need to end the combo and get out safley, you should't really have a problem starting another one up relativley soon. He's big, has lots of trouble getting around bacon, so its great in neutral, and for gods sake, DONT get hit by this <100% gettup attack, its so freaking big he'll use it every chance he can get, so learn the move and learn to avoid/bait it. He has a 1 frame upB OOS, whereas ours technically isnt till frame 8 (well the hitbox is frame 1 but you dont move till 8) so be careful when approaching his shield, especially with a lazy dair or fair, cause he'll just fortress, which is actually a kill move at higher percent. It also sets up great for his up air, which is a thing that should be avoided, as G&W is so light it'll kill at like 50%, combined with his downb jump cancel its a scary threat from below. That and hes got a nasty crouch cancel game, although if you want a laugh, waveland in, and just rapid jab untill he realizes he cant cc out of it and is forced to DI out. Generally good for ~ 20% at the start of a set, although they start to learn eventually. Bowser is among the many who can be jab reset after a dthrow, so make sure to abuse it if hes not teching. although all of our grab options are super good vs him, because anthing that puts him in the air for a unpilt up air or up b just freaking wrecks bowser, you can keep in him the air for a good while if your good about it. Just be mindfull of his combo excapes, nair is a popular one, as I said earlier, combinded with good DI, it can turn the tides pretty quickly.
Also just freaking beware of the moves he has that have super armor, jus being aware of when you can/can't challenge a move is half the battle. Off the top of my head, moves with heavy armor (cause technically they're not super) {dash attack, up smash, f-smash, d-smash- nair, side-b, and down b (when falling) }
On last thing to note, is make sure you have some crisp edgeguards, as if you mess up, you bear the risk of taking upwards of 30% from bowser's up+b if you don't SDI out of it, and I've seen many people carelessly try to fair bowser during his recovery, and taking alot of percent very quickly becuase they forgot to be smart.
TL:DR: **** you I wrote that you go back and ****ing read it if you wanna know what I said.
But basically just play smart and same, and you should have a relativity easy time.
and for link idk, just like, grab bombs with wavedash, throw them back, and dacus when hes in hitstun. Then tauntspam cause you are god and he is simple servant of lesser men.
