how to be the best there is at xenoverse

train under cell (assuming you didn't inherit his learned skills from a previous character)

make sure your only moves are perfect shot, maybe sledgehammer, maximum charge and supernova cooler

max out your ki blast supers/basic attack as much as you can (complete with qq bangs and all)
and turn golden if you are a freezer race

if mira (or pretty much any expert mission boss at all) uses his peeler storm block as soon as you can

make sure you have buddies helping you so the bots don't punish you for spamming perfect shot

know your recoveries so you can use perfect shot at the right time

congrats you are winner

try using those ki blasts if you can turn gold
