My torterra has awesome speed and attack he pwns every one with
his earthquake. I would suggest speed. A good moveset would be
earthquake, energyball, stone edge, and wood hammer/razor leaf.
Earthquake becuase well it is an awesome move with stab easily
pwns any non flying/ levitate/grass pokemon. Energy ball becuase
some pokemon have extremely high defense so a special attack is
good for a just in case move. Stone edge for type coverage for all of
his weaknesses look it up fire, bug, flying, and ice. Wood hamer/
razor leaf you need to compliment his attack with a good phyical
grass type move.
