In the first few matches, you lost your Cap because you dropped a combo. Just work on landing those more consistently during matches (you made Cap infinites). Also work on getting more damaging/optimized combos from your confirms.
Other than that, try to be more active (i.e. movement, utilizing double jump). And work on your blocking in a polite way, as you got opened up a few times but raw attacks such as Dr Strange’s crouching hard.
Is the opponent in the corner pre back throw or post back throw? Meaning are you throwing them out of the corner and want them back in or throwing them into the corner and want them out?
Sorry don’t have a console on hand so will can’t explore it much at the moment. From what I remember from when I was practicing tthe combos, you could adjust the bnb, from adding or removing attacks to side switching, to be able to land it.
Still, there is another video of someone else doing the double hyper charging star on youtube. HiI’mNasty has a video of five charging stars with drones too if I’m not mistaken.
