If I see a Poke I like, I catch it, keep it in my party for awhile until I find a better Poke that I like more, EG a higher leveled version or an evolved version with higher levels..Or some random Poke that looks cool, or a Poke that will help me on the next gym. The second Poke I kept was...Uhhh..The pre-evol of the pre evolved of Scolipede...*shrugs* my monkey I kept around for the first gym, PCed it, got a few Grass and Grass/bug Pokes in that one forest thing, brought out my Monkey again to PWN Cheren, PCed it, wash, rinse, repeat. But yeah..Im not one of the lpayers thats all about Poke that own certain gyms..I pick Pokes that catch my fancy ;)
