I feel like MK/Marth is even. Marth outranges MK and combos him much harder than MK combos him. If you mixup throws well getting a tipper fsmash consistently off MK at kill percents isn't very hard. However MK can't reasonably be edge guarded, while on the other hand he edge guards Marth really hard, so it's really a matter of position in the matchup.
Disagree, mk just straight up outclasses Marth. Better grab game, faster, with just as much range. Marth has always had problems with characters that go in and Metaknight is one of the best at it. Anytime Marth whiffs an attack he will get punished super hard, and if he doesn't throw any attacks out he is still losing in the neutral. Meta knight has a much better punish game than Marth. His upair will literally carry Marth to the top of the stage where mk can just up B for the kill. He also has an insane tech chase game combined with his superior edge guarding capabilities. As long as the mk player Di's properly he shouldn't be getting hit by a tipper off a throw. From experience, Metaknight destroys Marth.
From my experience and matches I've seen. The Marth and Lucas matchup is in Marth's favor. Lucas wants to get on your sheild to start his insane sheild pressure. Marth can keep Lucas out of that range. I like to think of it as a Marth vs spacie match up where the spacie can't shoot lasers to force Marth to sheild (Marth can easily swat PK Freeze away with his sword). This gives Marth a lot of control over space which really hurts Lucas's limited range.
I disagree with this one too, although I think this much is much more even than mk vs Marth.
A problem I see a lot is people saying Marths range keeps characters out, which is what makes him win the match up. But his range comes at the cost of laggy moves.
For example, Pikachu has a tiny range while Marth has a ton of range, but pikachu still wins that match up, and Pikachu can't even use his projectile in the neutral. Even though Marth has a lot of range his moves are slow and laggy, and he doesn't have any decent oos options. Lucas, Mk, and Pikachu are all fast enough to punish Marth's laggy moves, and they also win in the neutral and can apply shield pressure that is tough for Marth to deal with. Not to mention they all have strong crouch cancel games.
Marth can swat away pk freeze, so what? You just threw out a laggy attack to stop a projectile that land cancels against a character with insane punishes and pressure. If you ask me, wd oos is much better option for dealing with pk freeze.
I think Marth's range is way too overrated, there are ways to get around it.
