How do you become a good player on rumble fighter

Watch videos on Youtube about your scroll and see if there are any combos you can do.
Guard after you finish an attack/combo.
Buy items that increase stats.
Ledge people by ramming or throwing. (Only do this if you want to be labeled as a garbage noob over and over again

Then, you'll get use to it in no time!
(I'm a lvl 12, but I go into the Open Channel, go against lvl 30's and win 100+ points ahead)
