Describe the Bug:Hateflayer's ability does not untap it (although it can't be activated unless it is tapped). Thus once it is tapped you can use its ability more than once.
Which card did behave improperly ?Hateflayer Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)July 2013
What exactly should be the correct behavior/interaction ?Part of the ability's cost is untaping it.
Are any other cards possibly affected by this bug ?anything with the untap symbol potentially.
