Seed Bomb-Deals with ground types.Has high Power and accuracy.Keep it!
Charm-Lowers the foe's attack by two stages,making up for Pachirisu's lower defence.
ThunderPunch-Since your Pachirisu is EV trained in attack,I would keep it.
Super Fang-Keep this too,because if you want to get a battle done quickly,you just use this twice.
I know this is mainly all the moves you have chosen.But with one difference,Charm.
