Let's see... my team would probably look like this:

(my top-second favorite Pokémon, right after Mew)

(one of my top favorite Pokémon - my OC Cerise has a female one... in my RPs and fics, it's the mate of Riley's Lucario~)
:crobat: (I always have a Crobat in my team when I play the games - don't know why, maybe because his Attack stat is so high?)

or :volcarona: (since I'm OCD and don't want two of the same type - Houndoom used to be my top-third favorite, but Volcarona is rising on my list...)
Saving the other two slots for XY Pokémon.
