i tend to just wait for an opening against kano and then hope i get lucky, i generally stick with 21 exrune online just to ensure they cant get an upball out and interrupt me
if they spam upball, and you are online and its not a perfect connection: bend over and take it you can try uppercut but it will most likely be blocked, offline uppercut should get it every time
thinking more about it, i wonder if upball will go over a d3 or still hit you
it probably wont work against kano very well, but i have had success against rangers recently by using trance right after jumping over a projectile
you can also just try to avoid kano players online, thats been my favorite
