@ Huggles and Ryos:
Thanks for the advice. Wifis are bad for critiques, we played several other others where I lost that exceeded 3 minutes.
Small stages, especially YI (brawl), make it hard to space without getting edge pinned so I tried to keep away from ledges. My wifi DI is worse and an aggressive Marth's hard to space anyway. I never play Marths so he's almost as hard as MK for me.
Rolling past Fairs is good advice. I tried to airdodge that intercepting Fair but the lag made it too late. Marth approaches fast and has a major advantage up close. TBH, he was a good Marth but the only replay I could save was c****y. Wifail's obviously a large factor but at least that lets Dairs connect.
-------------------------
I HATE Ike on wifi, offline he's manageable. Does anyone feel this way about certain MUs?

My strategy is use a good attack for the situation and not save kill moves because Link has so many. Fsmash has great range and auto turns (using 'C' for smash) for attacking after small retreats. Dsmash is fast. I can Zair/Bair/Nair/jab/spam them fresh or kill with Spin attack/Utilt/Ftilt/USmash/Fair/Dair/Uair depending on what is fresh. Plus Fsmash2 is always fresh as a spotdodge punisher, so I'm willing to deal damage with kill moves.

Edit: The Lucas match I was rusty and spamming stupidly. ^This strategy is better shown in the Lucario one.
I can't get a decent Marth match up
