Florges protects Alakazam from Charizard and Roaring Moon.
Keep Alakazam on the bench with Mimikyu, Flutter Mane, or Flefki in the active spot.
Attack with Alakazam's Dimentional Hand from the bench. If your opponent switches your Alakazam to active and puts damage on it, consider retreating back again to attack from the bench instead of using Mind Jack.
Don't forget about the Devolution tool. It can be really useful in the late game!
