What are some bad matchups for Marth? 3.6

[Qphex]

I want to know when to switch to fox.

Marth has very few bad matchups. The only one that Marth should be afraid of, honestly, is Dedede. Even then, Marth can absolutely bibbity-boop a bad Dedede.

Marth has this sort of property where he can really have no very bad matchups. He can almost always win by simply spacing better. If you have a fox as well, I'd suggest it for characters like Puff and Peach, as well matchups you may just hate. When I play Marth I hate Sonic, so I would switch for that MU. It's a matter of preference.

I don't think Marth and Fox cover each other very well in this game. That said I would switch to Fox vs:
Metaknight
Squirtle
ZSS
DK

Maybes:
Ike on large stages
Link
Puff
Falcon

It's not that these are bad MUs for Marth per se, but I think Fox has much better consistency, especially with punishes, while being equal or better in neutral.

fox is also a lot better vs yosher

 

[bboss]

Play Fox vs. Sheik, Puff, Link, Dedede.

If Fox's Uair kills off the top from a fullhop under 100%, pick Fox. That's how I do it anyway.
