Agadeem Occultist — ruling 1

You may target any creature card in an opponent’s graveyard with Agadeem Occultist’s ability. You check whether the targeted card’s mana value is less than or equal to the number of Allies you control when the ability resolves. If you control too few Allies at that point, the ability does nothing.
