Is Pokemon XD Gale of Darkness hard?
Definitely Colosseum and/or XD: Gale of Darkness for the GameCube. In those games, not only are you limited to a much smaller number of Pokemon you can actually use, but many of the battles themselves are damn hard and catching Shadow Pokemon is a pain.
Why can Rui see shadow?
Rui supported Wes in his quest to defeat Cipher and Team Snagem. Although Shadow Pokémon are usually indistinguishable from the regular kind to normal people, Rui is able to sense a black aura surrounding them. Using this ability, Rui was able to identify Shadow Pokémon so that Wes could snag and purify them.
