Any early guesses on Mr karate? He seems like he can really maul once he gets in
crossup after reset can be quite brutal, but once you're used to the matchup his low reach (aside from far C->f+B) is really a downside. He seems like he's particularly strong vs. low level players who get caught off guard by his resets and his unblockable. Personally I think Takuma is stronger overall since he has the command grab, and somewhat better damage with meter and higher damage HD combos (for now).
Don't get me wrong, Karate is a goddamn beast for damage and has just as many options as Takuma, but he loses lots of his tricks against people who know his gameplan whereas Takuma is a bit more unpredictable. But who knows, he's only been out for a couple days, he certainly has room to grow and gain new mixup potential. The fact that he doesn't have as high damage and lacks a command grab over Takuma is kinda painful at the moment but he's still crazy good. In terms of defense Karate beats Takuma hands-down. Invuln shoryu, EX counter for a full combo, or early Brake shoryu for some severe anti air damage are all crazy tools.
Of course I haven't really played AS Karate much, just done his trials, but I've been playing against my friend's dedicated Karate main all day. I don't know all that much about the character aside from what I've been taught over the course of today.
