Oshawott has Electric and Grass.
Snivy has Poison, Fire, Flying, Ice, Bug
Tepig has Rock, Ground, and Water, but as an Emboar has weaknesses to Flying, Ground, Water, & Psychic.
Hope I helped! I recommend Oshawott for in-game play...
EDIT: Thought you might want these links. For Oshawott, Snivy, and Tepig. :D
