don't chase MK in the air unless there's a banana somewhere in the mix, if it hits you can combo, if he catches it with an aerial then he can't swing his sword to cover his whole underside so aim for the blind spots, if he catches it with an air dodge punish out of it. this is how you lost your first stock game 1.
use more dtilt, great spacing tool. I'd use more jab in CQC also, the issue didn't arrive too much because Tyrant for some reason chooses to be in the worst possible range of Diddy (mid range mostly, with some long range).
could have continued banana lock across stage at 9:10
you suck at recovering, i'm not really sure how to critique it either, but I'm just going to tell you to go ahead and turn tap jump off as it'll help in the long run. The reason I know you have tap jump on is because any time you use up-b off stage with a jump stored you use the jump. Tyrant didn't really capitalize on the times it happened, but if you were hit out of up-b you would have been ****ed. If I'm wrong and you don't have tap jump on then stop being dumb and using jump + up-b anyway.
you were doing fine until you like started panicking for some reason game 3 2nd stock when you were around 70. He got a bit of momentum and then you started throwing out random attacks you died, then threw out some more random attacks, went in going super aggressive even though you have 6 minutes on the clock. You finally started trying to calm yourself down and get some bananas out, unfortunately this was like the one time the whole set tyrant actually punished your banana pull by taking control of the banana so it may have threw you off? Diddy has ways to punish opponents if he chooses to go for the bananas in the banana pull.
