Okay, so I know that in order to purify Shadow Lugia, you need to have all the rooms to max tempo. But I'm having trouble getting to max tempo. I've tried putting pokemon of the same type in the same room, (for example, I've put Magmar, Growlithe, Houndour, and Magcargo together) and it won't work! Is it because my pokemon are at different levels, or is there some sort of trick to it?
