Energy Ball: Covers Weaknesses, Overall Great Move.
Flemthrower/Heat Wave: I Think Shandeeras Sp. Attack is High Enough Where it would be better to use Flamethrower, for the accuracy, but, its your choice:)
Shadow Ball: STAB, Great Move, Covers Ghost.
Calm Mind/Psychic/Nitro Charge: Calm Mind For Raising Sp. Stats, Psychic for Coverage, or Nitro Charge to raise speed while doing damage:)
Heres Another Good Set:
Sunny Day: Uh-Huh
Shadow Ball: STAB
Items: Quick Claws for Both Sets, we need speed.
EVs: 252 Speed, 252 Sp. Attack, 4 HP
Nature: Hasty: For A Great Special Tank, and Sweeper at the same time, we get more speed, without lowering sp. defense:)
