I like to use 6B in this matchup because it can catch his full screen command grab if he tries for it. I believe you can't do it on reaction because at that point his command grab would already have hit you, so basically you want to condition him not to use it by tagging him with 6B enough beforehand. Also if there's a puddle on him i'd assume 623A/B would be good at stopping him from using that or pressing buttons in general. Also 236B is very important being it stops his flight dash in's and hinders air movement in general, giving you cover to get in. You can also just dash under his flight if anything. Aside from those two parts of the MU, his pressure will be something you have to deal with being Carmine with no reversal options, so i'd say to just be patient and look for any holes in his offense so you can then begin yours from there.
