>>44673072Pyukumuku can run very straightforward support sets (almost to the point that there's not much to say about it). It has the good basic support moves such as screens and Helping Hand. It has Soak and Pain Split for disruption, and the latter can be quite annoying considering Pyukumuku won't die so easily unless targetted or taunted, which would help in giving your partner free rein for a turn. A surprise Memento can't be underestimated as well, giving its partner and the following mon a considerable amount of momentum (along with potentially halting Dynamax momentum if you play with it on). If you want a more basic approach, it can be an annoying debuffer with Screech and Tickle, and it is also fortunate enough to be one of the few mons to keep Toxic, but its use would require some more forethought considering the faster nature of Doubles. Gastro Acid can be used, but there are not many situations where it would be more useful than just dealing with abilities in other ways outside of the surprise factor.
All in all, while you can't quite build a team around it, it can fill the role of a supporter pretty well, and its presence in the field is something a lot would be caught off-guard by.
