The little I gathered from watching Hyde vs Merkava is that you don't want to force your way in when he's outside of your pokes and fast flying into divekicks. That's usually bait to make you throw a Dark Orbiter or rush in. Do either of them recklessly and you're likely to get hit by his glide attack or a long limb into a combo.
Merkava seems to be at a disadvantage when he's inside Hyde's pokes/pressure range. You can bully him a bit and slowly push him into the corner. Once Hyde has meter or Vorpal he should have 2 or 3 chances to land some hits and knock him down in the corner. It seems like he doesn't have a reliable reversal as well. But, be wary of going for a tick throw because he'll divekick you into a combo and then probably a left/right mix up.
Also, Merkava's pressure doesn't seem so scary on block. He slowly pushes you away without a solid option of getting in your face and re-applying pressure.
This is just from what I've seen in a few matches. I could be wrong about some things. I hope you guys correct me if I am so that I understand the match up correctly.
