Hey guys Dr.84 here and I was just wondering what are some things that beginners like myself can do to improve their runs any tips/tricks like what combos to practice would be appreciated?

Hey guys it's Dr.84 here. I wanted to ask what are the rules as far as running this game (Can I use Capsules? What level do I have to be? Does it matter what system I play on? etc) . I plan on steaming my runs so I don't want to break any rules or violations.
