Ah, excellent. I can assure you that Ralts is an excellent addition to any team, regardless of which form you choose to evolve it into.

[As for the other two, he has no experience with Espeon and Munna? ...Well...]

I must admit I'm surprised by your second choice. Munna isn't a particularly strong Pokémon, but I'm certain you can find a use for it. How have you been enjoying them so far?
