"Also, do you think my team needs a Shuckle? He seems pretty good in a SS Team. He could replace one of my walls. The only problem is his **** offense."
Ehh... Shuckle. Godly Sp. Def especially in a Sandstorm, but most of his options are gimmicky. He Toxicstalls worse than Probopass. What I've long wanted to try is a Power Trick set: switch into a special-based Pokemon that doesn't have a Water-type move (i.e. Porygon-Z, Charizard), Power Trick, and hit hard. Still, Shuckle generally sucks. I would advise a Lucario or Empoleon since your team is lacking on the special side.
