Also note some important downsides to other status inflictions:
Burn: Pokemon that have Guts or are Fire types are immune.
Paralysis: Pokemon still have a 75% chance of attacking, plus some of the really fast ones are able to still go first, as do priority moves.
Poison: Poison and Steel types are immune.
Sleep: Pokemon can still use Sleep Talk.
Infatuation: Pokemon of the opposite gender and genderless Pokemon are immune, whic makes this really useless in the Uber enviroment especially.
Confusion: Ends when the Pokemon switches out, and only lasts for up to four turns. The most reliable way to confuse (besides the rare Teeter Dance), Swagger, also raises the foes Attack.
Curse: Can only be afflicted by a Ghost type and really damages the user.
