Without 50 meter to RC your unsafe stuff you are left with not much. It's all about doing stuff and analyzing the opponents reaction to it and counter it. I know for a fact that 236D beats most supers and every DPs except her own and Tsubaki's. You can also 214A~C~delay to fish a free CH Mars Chopper or Star Gazer, it's beauty is that no RC is required to combo off a CH Mars Chopper, but is needed if its blocked. 214A~B is clearly unsafe and you'll most likely get 3C'd by a DP masher and he won't even hit confirm it because its a fail option select. Now that we lost 5B JC we're stuck with 6A and its super small hitbox that might whiff if used too late in a blockstring. Have fun.
