Nice, congrats. I know it's not an easy road with Yoshimitsu, to be honest I don't think I've matched against a single solid Yoshi so far.
Also, don't underestimate Guilty Gear players, that game is no joke to be good at, it's seriously hard. But yeah Tanukana should've won that.
As for me I've been playing Guilty Gear lately to get used to the arcade stick better. Tekken is an awesome game but input wise not that demanding, so I needed something to force me to learn more special inputs and I love the GG aesthetics.
