alakazam fall to swellow, and the large amount of priority users, other than to half of the scarfed:
Extreme speed arcanine, technitop, scarf absol, and un-seen sucker punches from Hintmonlee... blastoise can take any hit and roar out, so does milotic (surf back), umbreon can wall it, but must get in on pyshich and should avoid Focus blast (yet, it can survive and 1hko back with pay back).
Then there is mr spiritomb, that says hi and kill it with pursuit and sucker punch.
Porygon... half of the tier is faster and when it's not it's choiced, so, ghost and steels kill it.
