Wobbuffet

Due to its access to Shadow Tag, Wobbuffet stands as one of the main trappers in ADV Ubers, along with Magneton, Dugtrio, and Umbreon. Wobbuffet separates itself from the other trappers with its superior bulk and the ability to immediately trap any foe. Shadow Tag has no limitation on what can be trapped, which allows Wobbuffet to remove at least one opposing Pokemon in most games. In addition, Wobbuffet's access to Encore prevents it from becoming setup fodder. Encore in conjunction with Shadow Tag can provide teammates with valuable setup opportunities as well.

However, Wobbuffet's utility in ADV Ubers is limited due to the overall lack of Choice Band users, as Pokemon that can utilize Choice Band often prefer other items. In addition, most Pokemon carry at least one non-damaging move, which forces Wobbuffet into mind games with Encore. Its passive nature is also exploited by some setup sweepers, meaning that one incorrect read can prove devastating. While Wobbuffet's bulk may ease predictions, its inability to hold Leftovers limits the number of hits it can take: Wobbuffet is banned from holding Leftovers, as Wobbuffet vs. Wobbuffet will always result in an unending battle due to ADV's Struggle mechanics.
