i went with treeko. this is watll be like wen theyll evolve
marshtomp-water/ground 3rd evolution (forgot name)-water/ground
use sceptile for the mossdeep gym
mossdeep is physcic >_>
so what do i use?
well actually grass works on their pokemon because their not only psychic their rock and grass is super effective against rock.
but if you really wanna beat a phychic you need a ghost or dark pokemon....the only weaknesses of a true psychic
