I won my 1st Poke Gym in my Level 12, and what did assign in my Gym?
A Weedle CP37, ahakss.. That's what clumsiness do to you.
My second Gym, I assigned a Vaporeon CP864.
Now I am at level 17, I am going to post about my Gym journey for my future amusement. If you are not a Pokemons fan, you can skip my Pokemon Go posts ya ;)
