Just suggested Prismatic on the off chance that Stone Striker gets removed. Then you're hosed or hopin' it's Earth based damage you're facing, not Physical or something else.
Convert Hexes is nice. How often in GvG do they hex stack though? I usually onto run into one hex at a time unless I'm playing one of those Life Transfer necromancers (Or the -6 energy Degen necromancers I face in RA).
... What about... Reverse Hexes? Same thing I seem to remember but give you a little RoF effect for removing hexes rather than +armor per necromancer one.
