I have four different movesets for him. One is a supporter moveset while the other three are special sweeping movesets.

Role: Supporter
Alakazam @ Leftovers / Alakazite / Light Clay
Ability: Magic Guard
EVs: 252 HP / 252 Spe
Timid / Jolly Nature
- Wonder Room
- Reflect
- Light Screen
- Recover
- Wonder room: switches the defense and special defense stats for all Pokemon for 5 turns
- Reflect: Halves physical damage for 5 turns (8 with light clay)
- Light screen: Halves special damage (8 with light clay)
- Recover: restores 50% of your entire hp.
Strategy: This set is pretty good if ya ask me. Here's how it goes. depending on what kind of sweeper your up against(physical or special) or depending on how bulky the Pokemon is if its more defensive or more special defensive, you will use wonder room. reflect and light screen are for decreasing the damage you take and recover is for restoring the damage you lost. For single battles and rotation battles you don't want to keep Alakazam in forever so its best after setting up and gaining back some of your lost damage that you switch.
Role: Typical special sweeper
Alakazam @ Alakazite / Leftovers
Ability: Magic Guard
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Psychic / Psyshock
- Dazzling Gleam / Signal Beam
- Shadow Ball
- Calm Mind
- Psychic/Psyshock: psychic for more damage and 10% chance to lower special defense or psyshock if ya wanna do physical damage.
- Dazzling gleam/signal beam: Dazzling gleam does slightly more damage and is a fairy type move but signal beam has a 10% chance to confuse and is bug type (either way both moves cover dark types)
- Shadow ball: covers ghost types and 20% chance to lower special defense
- Calm mind: Raises special attack and special defense by one
Role: Fast specs
Alakazam @ Choice Specs
Ability: Magic Guard
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Psychic / Psyshock
- Dazzling Gleam / Signal Beam
- Shadow Ball
- Trick / Energy Ball

Role: Stab Sweeper
Alakazam @ Twisted Spoon / Alakazite / Leftovers
Ability: Magic Guard
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Wonder room
- Psychic
- Psyshock
- Calm Mind
strategy: Perhaps I should explain. Psychic is used against Pokemon with less special defense and psyshock is used against Pokemon with less defense. Wonder room is for protection purposes in case you are up against a strong physical sweeper. Calm mind is self explanatory.
