How would a dual screens set fare on Klefki?
Compared to Deoxys-S, it offers more defensive synergy and team support (like Prankster T-Wave is still really good in checking stuff like Xern), and has a larger chance to set up more than once due to a much better defensive typing. When compared to Deoxys-S, its main downside is the lack of Taunt and Stealth Rock. But Thunder Wave is a pretty good discouragement against a lot of common Defoggers, including Lati@s, Gira-O and even Arceus forms. And there are SR setters that can maintain offensive pressure (like Pdon, surprise!) to accompany it.
