How about having a trophy for having so many of certain types of Pokémon and not just for catching so many Pokémon?
Just their typing like Charmander, Ponyta, and Houndoom are all fire types, then maybe if I caught say 5 fire typed Pokémon then I could get a trophy for catching 5 fire types.
That's a pretty good idea. Whilst I don't think the current trophies should be changed much or removed, I'd be happy to add some of these. I'll look into it.
