Though now I think of it, the hexproof is nigh useless if it’s not at instant speed. Granted, seeing as it gives everything hexproof it’s not risking getting 2-for-1’d, but still, sorcery only means that unless the removal was attacking creatures only, your guys are just as dead as if they didn’t have it.
It does demand an immediate answer, and if you’re casting it, you probably have a big enough board that you won’t mind one or two losses.
And if your opponent happens to be tapped out, or topdecks removal next turn…
