Shiftry

Although it has suffered in UU, Shiftry finds a unique niche for itself in Ubers. Its access to Nasty Plot, Swords Dance, STAB on both Grass-type and Dark-type moves, and blistering Speed in the sun make it a good choice on Drought-abusing teams. However, Shiftry is quite literally a fair-weather friend: if rain, sandstorm, or a Pokemon with Air Lock is on the field, expect a speedy demise for Shiftry. Even in the sun, Shiftry can be countered and walled, so do not overestimate what you can do with it. Nonetheless, if you give Shiftry the support it needs, you will be pleasantly surprised at what the Chlorophyll abuser can do.
