I'm in favor of banning it. It's possible to play around it, but you can't 100% beat it due to the nature of confusion. If we're going to take this to an extreme example, I don't think anyone would be pleased if a SwagPlay team ended up at the top of the ladder because the player managed to be lucky enough to beat all opponents without any skill. I don't oppose it because it's unfair, really, just that it does not require skill to build or use one of these teams so having them on the ladder can potentially impact the ranking and success of people who are actually good at teambuilding and prediction. I wanna say there was a guy around 1500 in rank using a full SwagPlay team, which means he beat a considerable amount of people purely through luck.



However, I don't think banning Pokemon is a good idea - Klefki is an awesome Dual Screen and Spikes setter and it would be unfair to remove his utility in that capacity due to the possibility of a SwagKey set. Outside of SwagPlay strategies, does Swagger really have any use? Confusion on its own is a pretty unreliable strategy with its possibility to not work or even just wear off immediately, so I don't think the metagame would really be losing anything by banning that move beyond dismantling the SwagPlay strategy, as intended.



Overall, it doesn't really hurt the metagame to ban Swagger, and it removes the option for lucky players to triumph over skilled ones. Much like uber Pokes that allow you to just run a train over your opponent without any skill required, this strategy does the same, and though it's not as reliable as, say, Arceus EKiller in OU, it's also not possible to ever reliably counter it due to the nature of confusion.



tl;dr Ban Swagger
