Double jumping huh? Careful with that.. That habit of DJing after getting hit needs to go.. or even just DJing when the opponent is near.
Very good to juggle opponents and also to put opponents on platforms... both instance you have to hit it on the first hit. And putting people on platforms = easy techchase read. Downthrow into Nair on works at 0 on Marth, Peach for example. Usually it's good to do on floaties at low % since you can pop them up then put them in a bad position or at mid % on fast fallers for juggling too.
Actually at GOML vs Juggleguy.. he ledgejumped then I chased his jump with double hit Nair into DJ fair off-stage and killed him at 50%.. lol. (True combo with the DI) There's probably still hidden uses for it as you Ganons refuse to use it for whatever reason.
Actually, I started to experiment with it in other ways yesterday. I like to throw out uairs vs fox in case of an areal approach, but Ripple started noticing that I did that, so he would wait for the uair and then come in and punish. Nair will trade with a fox approach and doesn't allow for fox to come in and punish the same way as he would normally for a whiffed uair. He got hit by it a couple times. It's not super viable, but it's definitely a mixup if you're getting punished on your uair game.
And DJing after a spot dodge is relatively safe, right? 99 times out of 100, they're in their shield after a spot dodge and you're in the air as ganon lol. But you're right about DJing in general. I do that way too often after I get hit and then all I have is that ****ty up-b recovery.
And jiggles, you're gonna get demolished. Absolutely and utterly *****. It's cool, it happens to everyone at their first tournament. But learn from it, don't get discouraged (like I did lol) and get the chance to play as many people as possible and have them give you tips on your spacing and fundamentals. Tournaments are easily the thing that has made me improve more than anything else. Good luck and have fun!
