stoneskin+shield is powergamey? Oi.. Against commander when even black sanc+haste is not enough to outdamage him in one fight? Well..actualy if you want to play sucky chars(in PK) then yes you don't need even basics like flight and enlarge/reduce otherwise you can't succeed even bit in Cfs PK without being able to collect at least stoneskin, protection, enlarge, reduce, fly, return/teleport potions. Or you addicted to play only ragers.
