EndQuote, take Suprise the Sableye. It's item is Leftovers. Brave nature. Ability is Prankster. Min of 150 evs in HP, 50 in ATK, and the rest is up to you. Must have will-o-wisp, recover, and Knock Off. Final attack is up to you but may not be status.
Edit1: Got tired of hunting a Scyther with the ability Technition. I traded over one with that ability and a Metal Coat. I now have Reaper the Scizor. I am currenty training TucknRoll the Sandshrew for his solo of Whitney.
Edit2: TucknRoll has soloed 4 Magikarp and 1 Sandshrew with only Rapid Spin. He has also soloed 8 Rattata, 1 Ditto, 1 Abra, and 10 Drowzee using only Rollout. His evolution requirements are completed. Time to go solo Whitney.
Edit3: While battling gym trainers, Tucknroll finally evolved!! This will make soloing Whitney with him so much easier:)
