Porygon2 to UU/BL - It really doesn't have a place in OU
Cresselia to UU/BL- Probably would be one of your best physical wall in UU or BL, but in OU is easily dominated
Murkrow to NU- Only perk is Prankster otherwise poor defenses
Exploud to NU- Again, this is out classed EASILY by Sawks
Sawks to UU- Due to the uber powerful Sturdy+Close Combat
Simisear to NU- This is outclassed easily again.
Haunter to LU- Easily can stand most of the LU threats and outclasses most NU Pokemon
And finally..... MAGIKARP TO UBERS! (I had to... xD)
