Alakazam@Life Orb
Ability: Magic Guard
EVs: 252 HP/252 SpA/4 Spe
-Protect
-Torment
-Psychic
-HP Fighting
This set allows you to essentially devastate an opposing mon. This allows it to beat Ttar without risking issues of Focus Blast accuracy by Tormenting it so that it can't Pursuit every turn and OHKO with HP Fighting
252 SpA Life Orb Alakazam Hidden Power Fighting vs. 180 HP / 0 SpD Tyranitar: 411-484 (106.47 - 125.38%) -- guaranteed OHKO
It escapes a pursuit trap by tormenting, protecting and then OHKO
This set also has the ability to Torment other pokemon like Volcarona who can then no longer beat Alakazam thanks to Torment/Protect
I'll be honest and say I strongly dislike this set, for the reason that Alakazam is not suited for Torment stalling whatsoever. It lacks resistances/immunities and has almost no bulk to speak of, even with full HP investment. What made sets like Torment Heatran work was that a large proportion of the metagame at the time only had one move that could deal enough damage to even break its Substitutes, and hence it could be virtually invincible under certain circumstances - and especially potent with Toxic Spikes down.
As Alakazam does not possess any of these qualities, the only chance it has is to stall out choiced 'mons, and even then you still have to predict to use Torment on the switch-in. My main problem with this set is that it's
highly situational, and ineffective most of the time. You can't guarantee that the opposing Tyranitar will be choiced, meaning that you're just wasting turns if you use Torment on the switch-in and instead of attacking they use Stealth Rock. At least 90% of players aren't dumb enough to let you stall them out of Pursuit, and will probably switch out as soon as you use Torment in the first place. Also, what's the point of needing to use Torment to beat Tyranitar when you claim that HP Fighting OHKOs it? Why not just attack it as soon as it switches in? (FYI it doesn't, since you didn't take the SDef boost from sandstorm into account - whereas Focus Blast does, which you may as well use as it has a good chance to hit at least one time out of two)
I fail completely to see the reasoning behind this set. It doesn't accomplish anything useful - it just takes away from its coverage. If you're
really worried about Tyranitar, just use Dugtrio or something like Terrakion. Also, on a less important note, how the fuck does this Alakazam beat Volcarona? You Torment it, it Quiver Dances every time you use Protect, it kills you with either Bug Buzz or Fiery Dance ._.
EDIT: Apologies if this post seems a little harsh. I'm just trying to be direct with you so that you won't make similar mistakes in future. After all, knowledge is power - "The truth is that everything that can be accomplished by showing a person when he's wrong, ten times as much can be accomplished by showing him where he is right."
