I've got a hint for this match up. Don't use Gantlet Hades or the punch attack (sorry, don't know the name of it...) as an approach every time you start a match because most Carls will block or jump back in the air and block, then counter. Instead, you should try to fake them out (believe me, I know what I'm talking about. I played this guy's Ragna like 26 times and only won 6, which was when he stopped using that dashing punch thing...) with IAD into some attack or something.
I hope this helps a bit...
