Or Soul of Stone for that matter. I'd consider that a must have considering how nasty the miscasts can be (if it works). Cupped hands only works once afterall, and if they count the regular Miscast and the Fulcrim miscast as two seperate instances it's not as much use.
That is only for the normal spells true. All cataclysmic spells can NEVER be cast with IF and can NEVER be dispelled with IF.
