Yeah, marths best moves are more grounded (DB and probably dtilt). He can jump, he just needs to be aware of pikas options in that position. I can see marth winning more RPS exchanges between the two, what I dont see is how he limits pika to simply punishing mistakes (its not just marths, a lot of people seem to think this I think from a misunderstanding of how to play pika).
I understand your poiint about MU knowledge, the only thing Id say is that I think this applies to other characters too. Unfortunately Chaz and ESAM havent played in forever I think, but I think ESAM and Kadaj may be playing more frequently. Also I think mike believes the MU is even.
And as a resident of SoCal Im also
rooting pleading for marth to solve the diddy problem
.
ROB, Toon Link, Kirby, Mario, Ike, ZSS, Sonic, and Snake could be even on degrees of how broad even should be. But then I'd also be inclined to bring down GW, Olimar, and ICs. I wouldnt say any of those characters are hindered by the MU though.
ROB I can actually agree, but Im the lone voice here and some Pikas and even ROBS think this is +2.
PT I mostly agree with +1, but both sides seem to think if pika abuses fatigue its more a +2 which I find reasonable.
Lucas could definitely be +1, but I wont get into that, lol. Side note but ness would destroy pika if we couldnt grab release to edgeguard/upsmash.
Mario does exceptionally well vs pika. Both have fairly similar traits and pikachu definitely is no hinderance to mario. Pika does
slightly better in several areas that can put mario as a -1 when defined narrowly, but are negligible if more inclusive (making it 0).
DK and Pit I dont agree with. Not that they arent decent characters, but pika just tends to fill in the holes of their weaknesses. For those MUs to be better someone would need to revolutionize their playstyle to cover those weaknesses, which may or may not be possible.
