Look, this is the problem I have with Pursuiters, they are too few and far between. The only common user is Spiritomb. Yes, you have a few Drapion, Absol, and Houndoom around that run it, but they mostly use sweeper sets (SD/NP). Also, none of them can switch into Zam safely, which means they need to REVENGE KILL. Revenge kill = Zam already killed one Poke, and if you mispredict with Pursuit/Sucker Punch your revenge killer is DEAD.
Let's go. About Pursuit users:
They are few because they have better things to do.
Spiritomb and Skuntank are made for abusing Pursuit mainly.
I see those as the best Pursuit users out there (Spiritomb has more bulk and it's overall better, while Skuntank works for a quick Pursuit and Explode).
Anyway: Skuntank can switch into Psychic or sub, break the sub, and then...
I always used one to avoid being 2HKOed by 2 LO Thunderbolts from Missy ( or a +2 TBolt), and LO Signal Beam does 36.6% - 43.6% to it.
The spread was 228 HP/ 252 atk and the rest on speed.
Against this spread, Kazam can't get through. Or it switches if thankfully gets behind a sub, or it gets KOed.
It will have low health; but that's what Explosion or Sucker Punch are for (and consequently Skuntank has done it's job)
I know it isn't the standard one, but i think this spread is better suited for UU IMO.
PS: Modest Kazam does 40.6% - 47.5% to it.
Fail Bast can 2HKO, but in my defense it can miss too lol
Just wanted to share this. Considering only the SubEncore set.
BUT i know how Alakazam can be dangerous, and the SubEncore is very good at cleaning and dealing damage. Without priority, Scarfer or Pursuiter, Alakazam WILL be hard to take out.
I don't feel Alakazam is suspect either. It is very powerful one, indeed, but not "almost impossible to wall".
Also, it won't take any priority. Ever.
