the thing is, there is no way to quote un-quote "be good".

there isn't some magic move that beats everything. There's thousands of moves and that's what keeps the game interesting.

I don't know if it still exists, but there used to be a huge list of moves on a tori wiki. I used that alot when I was a new player. I've been playing for almost 2 years and I still haven't gotten it. Just, be patient.
