Aiser, did you say no to battlefield as marth...vs fox? jump cancel ALL of your grabs. You were doing alright with the edge gaurding till you randomly forward smash when he is no where near you. You aren't dash dance camping into grabs enough, ESPECIALLY when he techs/misses a tech, you should dash dance camp and just wait for him to do anything, then grab him, especially wait for side steps after he gets up.
Random forward smash that missed poor choice of dtilt to edge guard instead of fsmash, since spawn can't really recover without popping over the stage don't bother trying to dtilt, just split his furry skull, or edge hog if he is really low. battlefielded. you should stop messing up the dash dancing, since it's really easy. ****** kicks. No weak attacks when people are at low percents, that leads to ccc with a really good attack that kills you. Practice your double fair, since you messed it up a lot.
Spawn stop trying to shine spike. Then when you light shield edge guard and marth goes above the stage, edge hop back air not drill to random suck, drill to upsmash doesn't combo. Nice dd camp into a grab, then you fail at it and get upsmashed. D throw dtilt ftw. If fox is level with the stage, just walk over and split his skull open.
Aiser, you use the secret technique of waiting in all the wrong places. Like edge guarding, most of the time you just sit there when you could do something better, like edge hog and then get up and grab or something cool. Then you don't use it after you grab/throw, when spawn is on the edge, etc. I see improvement though, in just that one video, keep up the good work!
