explain these gengar-ex decks.

each one i come across loses. cause they dont think about there weakness.

if anyone seen gengar weakness its dark. yveltal xy, yveltal breakthrough, yveltal ex, can ohko it easy. specially xy yveltal and yveltal ex. 3 energies on both can ohko a gengar-ex.

what i dont get is why not try a better approach with it. his one move would do better then the hide and hit move to my opinion. cause if some uses lysande its game over for that pokemon and i see way to many depended on that one pokemon that if you take that gengar out they will quit. why is that?

if my mewtwo is ko i use my other pokemon to do the rest.
