Your B DP reaches Merk at the top of his flight. You can also DP him when he goes for a Dive, which is a luxury many characters don't have.
His reversal, assuming you mean 236C, is not plus on block, to my knowledge, just incredibly safe.
Definitely in his favour, but if you make good use of your DP and stay close, you should be able to handle it.
Oh, and 214B is pretty good at catching him trying to jump out of pressure.
