Magic Attack: Decree is a Magic Attack spell that can be cast in Chaos Reborn. It can be used on any creature or growth anywhere on the battlefield, but it cannot be used against structures. It can be used against Wizards, but it cannot kill a wizard - it can only remove 2 spell cards from a wizards hand.
It is highly effective against neutral and undead creatures, as well as Shadow Trees and Tangle Vines. It can only target one creature or growth, but has higher magic power than it's triple attack alternative, Justice.
