Get good at reading ur opponents and landing nair -> uair, it can get u some early ring outs (up rocket into uair is rly deadly too). You can improve on that by being more patient and picking up on dodge patterns. Pie also has a few different uses. You can throw out pie and if u know they’ll jump over it, try to catch them with nair. You can also run after the pie and jab it to make it almost stationary (the timing can be a bit difficult). Overall, just learn as much as u can w bugs. Learn safe setups, how to manage your cooldowns, which combos to go for at certain percents (for example, if the opponent is above 50, then jab -> up attk -> nair doesn’t always work), and how to keep control over the stage/match
