Description: Alakazam only needs one set to wreak havoc, and here it is. With high Speed, impeccable coverage, and Special Attack higher than that of Latios, Alakazam is a struggle to face. The choice between Focus Sash and Life Orb is critical; while the combination of Magic Guard and Focus Sash makes Alakazam a premier revenge killer, Life Orb allows Alakazam to hit like a truck without fearing recoil. Focus Sash is particularly useful, as it will always take two separate hits to take him down. It is important that you choose the item that fits your team, as the item chosen determines Alakazam's function.
Options: Hidden Power Ice allows Alakazam to effectively revenge kill Dragon-types, while Hidden Power Fire is useful to hit Steel-types that are not weak to Focus Blast, such as Genesect and Scizor. Substitute can be used over a Hidden Power, as it eases prediction significantly and provides Alakazam a form of protection against other revenge killers. However, be warned that using Substitute in tandem with Focus Sash will make it much less useful, and the lack of extra coverage can be detrimental as a revenge killer.
Counters: The eternal choice between Psyshock and Psychic comes down to personal preference. Psyshock is recommended as it is a useful way to get through special walls such as Chansey and Blissey. Psychic, on the other hand, is able to hit Pokemon such as Rotom-W and Gliscor slightly harder. However, Psychic does fail to OHKO Terrakion in sandstorm, unlike Psyshock, which OHKOes regardless of the weather.
