I just finished the first cup. Came in here for tips. Left as clueless. These cups are a freaking mess and unforgivable. Very hard to beat. UPDATE Thanks for the few likes. Here's the update. I've beaten all galaxy cups except the Champions. What a cheating *ss machine!
This one I completed just a few hours ago once I survived the championship mode on galactic I was like all done with the hard stuff now I can play the exhibition games for fun
