Porygon Z

The premier offensive duck of UU, Porygon-Z makes for an effective sweeper, wallbreaker, and revenge killer. It has decent Speed, an incredible ability in Adaptability, and a very high Special Attack stat, allowing it to hit extremely hard and relatively quickly with Tri Attack. After a Nasty Plot boost, there are few Pokemon that can comfortably take attacks from Porygon-Z, and after an Agility boost, not many Pokemon that can outspeed it. Also, because of its power and access to Trick, it makes for an effective user of Choice items such as Choice Scarf and Choice Specs. To back its extreme power, Porygon-Z has a wide movepool with coverage options such as Dark Pulse, Ice Beam, and Thunderbolt. However, Porygon-Z is rather frail, falling to any decently powerful neutral attack. Also, its Tri Attack is resisted by many common Pokemon in UU.
