I know how to use it. It's not like I didn't play gen 5. It's just a slightly better liepard. You throw a ditto into the team to force out anything that beats the keys and gets an attack boost. You add in something that can spread paralysis early so that klefki doesn't have to do everything on its own and you switch out of obvious threats like the ones I listed. It is not any better than I have described in the hands of most. I'm not going to lie to you though MagnetBoy, I am not an upper ladder player at all. I'm not the best battler. Swagkeys are really easy to use though. It doesn't take much effort at all. It is however tough to predict the opponent. That's a lot of the battle with Klefki. One battle I fought a guy who would switch back and forth between walls on a predictable foul play or swagger. Another guy had whimsicott and used Klefki as setup fodder since it apparently was running 0 attack IVs. Most teams have an answer to swag keys just like last generations whimsicotts and liepards. I'm not going to say I won't get better as I use the keys more, but I honestly don't find swagkeys reliable enough to use it over a more traditional mon. I loved how I could generally set up on a lot more than liepard ever could, but in the end it's just a high risk high reward gimmick. And when I say gimmick I mean it with the utmost respect. My time here today has been spent basically trying to show it is not an unstoppable force like some make it out to be. The comments on here make it seem like the second coming of gen 1 toxic wrap dragonite or something. Anyway, I see no reason for it not to be viable as a slap to the face of the enemy, but it should not be considered the end all be all of klefki sets and I personally believe that the screens set is better. If I seem passionate about it, it's simply because I a) don't enjoy battling against these things and b) don't find it to be "broken" in any way shape or form.
