After watching the second set, I realized you're good enough to learn some more tricks. If you are on a platform, wobbles are almost always escapable, only inescpable at ~110%. You just have to mash out of the first few hits, because if you do it too fast Nana will fall through the platform. Wavelands are extremely important, and you only did them in-between stocks... and they were perfect for how you need to play against IC's! Specifically when recovering against a lot of characters invincible wavelands, or
haxdashes are super important as well, especially over 100%. So in conclusion, waveland more, especially on stage, don't U-smash unless you're sure, grab the ledge, and PLATFORM CAMP AGAINST IC'S.
