Seriously, what does it take to beat this cup? I've powered through the others, and I can't breed Pokemon of my own right now because I'm still gathering all the things I need to restore my Gold/Silver/Crystal cartridges. And this is the only cup left for me to beat in the R1 version of the game before I unlock the Rival and R2!
How did everyone else beat it? Did you breed your own team? What did you use? Did anyone try just rentals? Which rentals did you pick?
