Wobbuffet

Although it might seem like Wobbuffet has dramatically fallen from grace this generation, not much has actually changed for the blue blob in Ubers. A common misconception about Wobbuffet is that Encore's nerf has greatly diminished Wobbuffet's utility, but this doesn't actually affect it much in Ubers. As Wobbuffet will almost always use Encore last--the main exception is against Ferrothorn--Wobbuffet's Encore will almost always last the full three turns, which is more than enough time for fearsome sweepers such as Mewtwo and Rayquaza to set up.

Don't let these setbacks fool you: while a variety of common Choice Scarf users, such as Palkia and Zekrom, plague the Ubers metagame, Shadow Tag means Wobbuffet does an excellent job of revenge killing them, allowing insanely powerful sweepers such as Mewtwo and Darkrai to crush the many teams that rely on Choice Scarf users to beat them! Wobbuffet's utility doesn't stop there either. Encore still allows Wobbuffet to aid in setting up sweepers, and with most Mewtwo forgoing Taunt this generation, Wobbuffet can now check most Mewtwo in the rain. Finally, Wobbuffet's classic Tickle + Pursuit strategy is still an extremely effective way of defeating walls such as Lugia and Blissey, opening up holes for the many powerful sweepers of Ubers to demolish even a well-constructed stall team. Overall, despite Wobbuffet's downgrades this generation, its amazing and unique support capabilities make it a fine choice for any offensive Ubers team.
