This is Hilt.
MetaKnight- B: Purple, Yellow, BlueW: White
Obvious reasons. Whites aren't a problem because latch isn't a problem.
Snake- B: Purple, Blue, Red W: Yellow
Diddy- B: Purple W: ?
Falco- B: Yellow, BlueW:
Ice Climbers- B: Purple , BlueW: ?
Marth- B: Purple, Yellow W: White
Wario- B: ?W: ?
Yellows aren't good in the snake matchup, I'll oftentimes toss them away in the matchup, actually. Against Snake you want to focus on dealing as much damage as possible, as you kill him a good 50% later than he can kill you. Yellow's range doesn't help a whole lot in the matchup, since either snake is going to beat out your attack or he isn't, regardless of range. Falco gets grabbed a lot, so blues. Yellows are self explanatory for the Falco and Marth matchup. And I don't know much at all about Wario, but I'm assuming Yellow.
King DDD- B: White, Purple, Blue? W: ?
Pikachu- B: Yellow, Purple W: ?
Olimar- B: Yellow, Purple W: ?
Lucario- B: Blue, Purple , Red W: Yellow
Mr. G&W- B: Purple, Yellow W: ?
DDD does get ****ed by whites, other two should be self explanitory. Same with Pikachu. Olimar's yellow fsmash is the best move in the matchup. Lucario's reasons are the same as snake's. GW gets ****ed by aerials, Yellows and Reds for that reason. And Purples are obviously broken.
Pit- B: ? W: ?
Toon Link- B: Purple , White, Red W: ?
Zero Suit Samus- B: Purple , Yellow , Red W: ?
Kirby- B: Yellow, Purple , Blue W: White
ROB- B: White, Purple , Blue W: ?
Rob has a hard time getting pikmin off and has to completely stop what he's doing to get them off. Reds aren't that big of a deal against him. Purples **** him up. Toon Link gets messed up by Pikmin Toss, so Purples and Whites **** him up and force him out of camping. Red is obvious. Zero Suit is obvious. Kirby is obvious.
Donkey Kong- B: Purple , White W: ?
Peach- B: Purple , Yellow, Red W: ?
Fox- B: Purple, Yellow W: ?
Luigi- B: Yellow, Purple W: White
Wolf- B: ? W: ?
Purples knock peach out of the air. As do yellow aerials. Reds mess her up when you can find an opening. Donkey Kong is obvious. Fox is obvious. Luigi is obvious.
Sheik- B: Yellow, Purple , Blue W: White
Squirtle- B: Yellow W: ?
Ivysaur- B: Super Effective W: ?
Charizard- B: Purple W: ?
Sonic- B: Yellow W: ?
Ness- B: Yellow Purple W: ?
Bowser- B: ? W: ?
Sheik is obvious. Squirtle is obvious. Ivysaur is obvious. Charizard is obvious. Ivysaur is super effective. Sonic is O_o. Ness is obvious.
Lucas- B: Yellow W:
Ike- B: Purple, Blue W:
Yoshi- B: W:
Mario- B: Yellow, Purple RedW: ?
Captain Falcon- B: ? W: ?
Samus- B: ? W: ?
Jigglypuff- B: Purple , Yellow W: ?
Reds don't do much against Mario. Yellows do. Purples do. Both are obvious lol. Rest are all obvious.
Zelda- B: Yellow W: ?
Link- B: Purple , Yellow W: ?
Ganondorf- B: Purple , Yellow, White W: ?
