what's w/ the random side-b's and dairs? o.o... lol. im also not too sure about using dk's jab much at all... it isn't very good.... idk lol.
you should probably work on your dash dance game, esp. against ganon. ganon's fair/bair are really good so you have to space him out well. it's a dumb match-up -.-
spamming bair is good and all but you should be spacing them so your opponent can't just hit you in between them.
you also seem to try to cargo u-throw -> u-air -> u-air from 0, which doesn't work on anyone. you kept getting hit out of it most of the time but you kept doing it.... usually i u-throw -> up-b or bair to put space between me and my opponent so they can't punish. just find something that works for you.
you should try using up-b out of shield sometimes. ganon just stood behind your shield one time and jabbed it over and over... even though his jab is fast, it does have some ending lag, and dk's up-b hits on frame 3, so w/ a jump cancel that's 4 frames. ganon's jab has 14 frames of ending lag so it should work fine, and since ganon is the tallest character you should be able to hit him.
if you're going to try to upthrow -> fair, do a full jump in the cargo first and then a double jump. the 5 or so frames it takes to jump from the ground is enough to let your opponent get out.
idk why you cp'd to mute city against ganon, the lack of ledges is really bad for DK despite the ground hitting him up, and the blastzones are far away which help ganon survive & recover w/ his down b. I'm not certain where I'd take a ganon.... probably Brinstar. I dunno, I'm really bad against Ganon, so whatever.
also, work on your DI a bit.... you should be surviving longer with DK's weight. that up-b probably shouldn't have killed you on mute city, and the fair near the end of the first match had some weak DI.
your dk's pretty good though =D **** them!
