So this trend of special Magic: the Gathering foil promo card printings found in booster packs will continue in Amonkhet. This time they will be called “Invocations”, like some Egyptian spell or sorcery cast to curse an enemy or to summon rain for their crops. In a similar manner, this special printing is like a commemoration for this Magic set.
