Personally, I find his play style to be fairly bland. No real tricks. Just a versatile "good at everything, great at nothing" keyword that is very forgiving of mistakes. It's a great starting Master to learn the game with. I never found him to be OP, but I also started playing just before all of the game stores had to close down and never got to play against people outside of my basement.
That said, I have thrown him down a few times, since. The fun thing for me about going between keywords is taking tricks I learned with one Master and apply the trick to another to see if it's viable. Then I play Misaki and lose. 🤣
