(Take this with a grain of salt seeing as we dont know how the doubles metagame will develop yet) from what im seeing, this strat might have some value in doubles uu or lower, but if your planning on using it in a non showdown format (standard doubles) it might just be better to run togedemaru if you want the lightningrod effect. I can see this being nitch in a rain team, using the electric tpe to bait out eq while pyukumuku counters. if you want to go for an attack nullifying team you may want to run a storm drain mon. seeing as you seem to want to use pincurchin you may be dissapointed due to its medeocre stats in what is usually a very harsh metagame. the combo of it lacking speed and hp makes it so that it has a tough time dealing out damage, seeing as how you usually want one or the other on every mon (a slow mon needs more hp because it gets hit more and a low hp mon needs speed in order to not get hit). pyukumuku also has problems, mainly due to the format you want to do this in, its slow and very stally, it can be completely useless in some situations (special poison/steel type to dodge toxic and counter) and most of its kit relies on the opponent attacking it. its basically just worse wobbafet with toxic and a death triggered counter. it isnt really a threat in any way and the opponent can just focus down your other mons while its out. usually in doubles, support pokemon do one thing, and then attack and pressure the opponent. alolan ninetails as an example sets up aurora veil and then starts spamming blizzard and fairy stab. pelliper comes in with drizzle and starts hydro pumping, pyukumuku... almost always relys on its teammates to get anything done and the effect is usually something that another mon does better. im not trying to be a jerk, im just trying to give some honest advice. best of luck with your team comp.
