Yeah I'm starting to rethink that, maybe not as much fighting as supporting like a Shuckle was meant to do. My move set is probobly going to be:
Rest
Stealth Rock
Toxic
????? (some sort of physical attacking move, Maybe Bug Bite)
My Shuckle's Nature hinders his Def. but he can still take a hit from my cousin's Lv.71 Mewtwo. I will also work with EV training it's HP and have it hold Leftovers.
