I don't see Hex at all necessary in this deck, If you need to drop your opponents abilities then you can just do a T2 Garb, so I could see taking out any Hex for some pokemon ranger.I am play testing a M Sceptile/ Garb and a Sceptile/Ariados/Vilplume and I have found the M Sceptile to be more consistent. But, this deck has a hard time, which I thought it would, against Darkrai/Giratina, does a 50-50 with M Scizor and if you have a bad start against Fire it's almost dead in the water. I have also thrown in Lugia Break and it has had its use for a one hit KO on Regice. I think a Ranger is a definite card in this deck. Maybe be ambitious and sub for the hex.
