Okay, a few things I noticed like, In the first match.
You need to mix up everything. You repeat the same stuff over and over. So after the first few setup moves of whoever character I had, I was able to literally combo off them.
Mix up your offense and your defense. There were instances where I threw you up into the air, you air dodged instantly, I regrabbed you on the ground. Upthrow again, your air dodge instantly again, I uair you. This happened like 5 times in a row until I figured "he wont do it again, no way", so I didnt attack, and you air dodged.
You need to work on using other moves, you like to use nair a lot and fair, which your usually retreating. You should be approaching and giving the opponent less room to move.
When you dtilt, you use it more then once, which is ok if it hits my shield. But if it doesnt, you want to follow up with a different move, dont dtilt again. Mixups include jab and uthrow, dancing blade upwards, exc...
You also need to use dancing blade in the air to help you reach the stage after being hit in the air. It throws off peoples timing, which is sexy.
Im not really big on wifi xD, but it helped you here. So if you wanna play again, let me know.
