Anguished Unmaking does not kill opponents first creature if it has hexproof. By paper magic rules it doesn’t say “target” so I expected it to work. Instead I just damaged myself 
Just making sure, was it Runaway Carriage?
That is consistent with everything else in game with ‘first creature’ though. Like bonds, claustraphobia etc..
No, Gaea’s Revenge. It’s too good.
