The PlasmaKlang I tested before States and today hasn't lost to any Victini techs, hammers, etc.In fact, today I went against 4 Victini techs in 4 decks, and didn't lose to a single one.
PlasmaKlang is a strong play because everyone thought it died week 3 and will tech for Garbodor instead, which is by far a larger, stronger threat. That being said, Garbodor will only be so popular as it is expected now, unlike during States. And you can only tech so much. The only deck that I find has a huge advantage against KK is RayEels obviously, and Garbodor is difficult but not impossible. Blastoise Keldeo can tech for Rayeels or Plasma Klang, teching for both would lose consistency. Tool Scrapper is a given in BK to prevent the Garbodor autoloss (it IS and autoloss without it).
I'm stuck between KK, B/K, Garbodor, and I think that's all. Unfortunately for 2 of those I need at least 1 beach, for BK I need 2.
