>You can swap Rental pass Pokemon in Gateway Coliseum permanently to beat the later Rank Stages without importing Pokemon
What the fuck, I played this game to death since 2007 with a bunch of hacked legendaries and I only just discovered the extremely fun Battle Factory Roguelike collection mode???
I thought they just gave you the rental passes so you could play the game and then the powercreep is a "go buy the DS games retard" flag
