Hey Yoshi mains, I was giving him a go tonight and I play PM casually but would like to become good and I found something neat with yoshi. If you double jump and do a neutral attack immediately after (A+Y simultaneously) the animation will cancel and yoshi will gain the height/acceleration of the double jump whilst doing the attack. This button glitch (along with all of the others in the smash series) has some great combo potential along with countering edge-guards, and because you are technically doing yoshi's second jump this glitch has super armor with it! I registered on smashboards just to say that. Please post if you find this useful or any other ways that this could be useful. Peace!
