Snivy line - Picked him for the current second playthrough I'm doing before I play B2, just useless. Once I got to a place where I had 3 other pokemon who were level 20ish he took a backseat to my power duo.
Audino - Rustling grass, excitement of it possibly being a really mysterious pokemon with a cool power......Nope! Just Audino. Caught it, had one battle, put it in the box. Now I use them to get rid of frustration and gain XP.
