Alakazam does not belong in B- with all those UU scrubs!
He has two main sets that are both equally great. They are the Life Orb set and the Sash set.
For the sake of simplicity, I'm going to go with the arguably better set, the Sash set. Keep in mind that since Alakazam has Magic Guard, it's Sash will NOT be broken prematurely.
The moveset I'm using is Psyshock, Shadow Ball, Focus Blast, and Energy Ball
: Loses with Life Orb. Wins with Focus Sash 68.8% of the time.
252 SpA Alakazam Shadow Ball vs. 252 HP / 4 SpD Aegislash-Blade: 308-364 (95 - 112.3%) -- 68.8% chance to OHKO
: Same as Aegislash. The Life Orb set loses; the Sash set wins.
252 SpA Alakazam Focus Blast vs. 32 HP / 0 SpD Bisharp: 724-852 (259.4 - 305.3%) -- guaranteed OHKO
: Not the best matchup, but Alakazam can 2HKO with the Sash Set if you don't get unlucky with Focus Miss.
252 SpA Alakazam Focus Blast vs. 4 HP / 0 SpD Mega Charizard X: 154-182 (51.6 - 61%) -- guaranteed 2HKO
: Yet another instance of the Sash set being superior. Guaranteed 2HKO and Alakazam finally gets the treat of using it's STAB.
252 SpA Alakazam Psyshock vs. 4 HP / 0 Def Mega Charizard Y: 166-196 (55.7 - 65.7%) -- guaranteed 2HKO
: Possible 3HKO. Can't win 'em all.
252 SpA Alakazam Shadow Ball vs. 252 HP / 252+ SpD Deoxys-D: 92-110 (30.2 - 36.1%) -- 46.9% chance to 3HKO
: 2HKO, but the most common Deo-S set can't 2HKO Alakazam without a crit.
252 SpA Alakazam Shadow Ball vs. 252 HP / 4 SpD Deoxys-S: 196-232 (64.4 - 76.3%) -- guaranteed 2HKO
: 2HKO. Although, Thundurus can cripple Alakazam with Prankster Thunder Wave (I think that Thundurus should be Uber, but that's another debate.) Although it should be noted that the common Thundurus set cannot 2HKO Alakazam without a crit or paralysis hax.
252 SpA Alakazam Psyshock vs. 4 HP / 0 Def Thundurus: 180-213 (60 - 71%) -- guaranteed 2HKO after Leftovers recovery
I will edit this in the future to include A+ and A ranks, but feel free to do some calcs yourself. I'm been calcing and typing for over 30 minutes.
Conclusion: Though Alakazam cannot safely switch into essentially anything, it is an excellent revenge killer, winning 1 on 1 matchups with 6 of the 7 S-Ranks (I'm counting Aegislash). So B- is too low of a rank for Alakazam.
