Specifically, a Fire type that is capable of learning Burn Up. There isn't a correct way to go about it, but somehow you need to be able to pass off Shedninja's ability to a pure Fire type. Setting this combination takes a little more effort than some other collaborations. Since then, there hasn't been a Pokemon with no weakness that could gain immunity through Wonder Guard, but what if you could make such a Pokemon and do it legally? We all remember the notorious Wondertomb, the hacked Spiritomb from Generation IV that had Wonder Guard as its ability? This thing terrorized the competitive scene for years, since nothing could touch a Ghost and Dark-type Pokemon with Wonder Guard until Generation VI brought in Fairy types. This combination also works with Passimian and its Receiver ability. Throw in a Pokemon with Dragon Dance to replace Oricorio, then your Muk will not only be dancing, but will also be able to attack and defend all at the same time. So, if Oricorio faints while Muk is on the field, Muk will immediately gain the Dancer ability. When an ally Pokemon faints, this ability is replaced by that of the Pokemon which faints. This regional variation of Muk gets the ability Power of Alchemy. Now, this ability isn't all that strong when paired with an Oricorio, but it can be incredibly powerful when given to Alolan Muk. Using a dance move through this ability counts as a separate move, so the originally selected move still goes through.

It allows Oricorio to mimic a 'dance' move, regardless of its speed. Dancer, an ability exclusive to Oricorio and its different forms. This combination, unfortunately, can only be used in Pokemon Sun and Moon or in Pokemon Showdown, as this team requires the use of Oricorio. Give either of these two Pokemon Round and Choice Specs, then pair them with a fast Pokemon such as Accelgor, who also has Round, and you can potentially down at least one of your opponent's Pokemon before they even have a turn. Likewise, Pixilate turns all Normal-type moves into Fairy-type moves.

With Liquid Voice, all sound-based moves gain the Water typing, giving Primarina STAB. There are two abilities that, when paired with Round, make for a broken combination - Liquid Voice and Pixilate, belonging to Primarina and Sylveon respectively.

However, it has the added effect that if another Pokemon uses Round in the same turn, the user will not only move directly after the first use of Round (regardless of their Speed), but the power of the second Round will be doubled. The move Round is relatively weak compared to most moves, with only 60 base power.
