I actually beat him, too! With a card he had to read! So pumped!
To be fair, in my core-black deck, nobody ever knows what I dropped face-down.
He plays just insanely neatly, like he knows exactly to the twitch what to do at all times, but with careful thought--other JP players just jam lightning moves confidently, but he doesn't hide that he thinks, and you have little doubt he just made the best move he could.
Yes, he won the match, but that's not the point.
