I came up with a way to always block MMH's teleport, I don't know how reliable it is.
Block low, and a moment after MMH enters the ground with the teleport, block forward. It's very similar to blocking DD's ES, the mid teleport will be blocked by blocking low, and by switching to blocking high to the other direction you block MMH's OH teleport too in a way that you can punish.
So tell me how practical it is in a real match. Doesn't sound too hard to me, and if it's good than here you go, free combo punish of your fastest poke (up to 8 frames)
