- Hidden Power [Ice] / Encore / Substitute / Taunt / Hidden Power [Fire]
Role: Special Sweeper, Stallbreaker
Equipped with a Life Orb, Alakazam is a terrifying special sweeper and stallbreaker. A blisteringly-fast speed tier of 120 lets it outspeed many Pokemon such as Mega Metagross, Mega Gallade, Keldeo and Starmie, as well as solid 135 Special Attack to top it all up. Magic Guard prevents it to be worn down by continual switches into entry hazards and the like. However, it does have extremely frail defenses, therefore making it extremely vulnerable to various means of priority such as Bullet Punch, Sucker Punch and Talonflame's Brave Bird, not to mention Psychic is a terrible typing both offensively and defensively.
Psychic is the main STAB move here, and is chosen over Psyshock for the increased damage output as well as the ability to hit physically defensive foes such as bulky Garchomp and Landorus-Therian much harder. Focus Blast deals with Dark- and Steel-types that Psychic misses out on, such as Tyranitar and Bisharp. Shadow Ball provides great all-around coverage with Psychic and Focus Blast and hits bulky Psychic- and Ghost- types that the aforementioned two moves cannot deal with. Hidden Power Ice is the main candidate for the last slot, boasting the ability to OHKO both Landorus forms, Specially Defensive Gliscor, as well as Garchomp and Multiscale-broken Dragonite. Encore has a secondary slash, and shuts down defensive cores such as Alomomola + Heatran effectively by locking them into only one move.
Other options include: Substitute, which allows Alakazam to evade Sucker Punch, status and scout the opponent's moves, Taunt, which denies opposition's use of recovery and status, and Hidden Power Fire, which OHKOs Ferrothorn and Scizor on the switch.

Role: Special Sweeper, Late-game Cleaner, Revenge Killer
Thanks to a unique ability in Trace, sky-high Speed and Special Attack stat, Mega Alakazam finds a great niche in today's metagame. Trace copies the opponent's ability, allowing it to revenge kill weather sweepers such as Excadrill, screw over Prankster users such as Thundurus and Klefki, or potentially obtain great abilities such as Adaptability.
Psychic is Mega Alakazam's obligatory STAB, and is chosen to hit physically defensive foes such as Landorus-Therian and Mega Venusaur harder as well as the increased amount of BP; however Psyshock is an option to deal with Specially Defensive foes such as Chansey or Blissey. Focus Blast provides good coverage with Psychic and deals with Dark- and Steel-types that resist Psychic. Shadow Ball hits other Psychic-types, which Psychic and Focus Blast fail to hit, such as Celebi and Jirachi. The last slot is really team dependent. Encore provides great utility by shuting down Pokemon such as Bisharp and Ferrothorn by locking them into only move; meanwhile, Substitute evades status and Sucker Punch and allows Mega Alakazam to scout.
Dazzling Gleam is also an option to prevent Mega Alakazam from being hopelessly walled by Mega Sableye as well as dealing decent damage to Dark- and Dragon-types such as Latios and Tyranitar. Taunt shuts down defensive Pokemon such as Chansey, Alomomola and Slowbro by denying their recovery and preventing them from inflicting status on Mega Alakazam. Hidden Power Fire is also an option over the former two, allowing Mega Alakazam to reliably 2HKO Scizor and Ferrothorn on the switch, as well as having more accuracy than Focus Blast to deal with Steel-types. Calm Mind allows Mega Alakazam to potentially sweep, especially against balance or stall builds; however due to its lackluster defenses Mega Alakazam does not find many opportunities to set up.
