Now, I don't want to actually speedrun Colosseum, I just want to get it done in the fastest way possible, including purifying every Pokémon. So, has anyone got any tips?
To just blast through the game, I've heard using Croconaw is effective, tagged with Espeon. But would this then add more time to purifying Pokémon afterwards?
I don't know if it's possible, but I'm not too keen on ending up just having to walk around for a long time like I did on XD to purify my Pokémon, and I know that purification actually happens faster in XD than Colosseum.
