Amonkhet is a Magic: The Gathering expansion block consisting of the sets Amonkhet and Hour of Devastation. Amonkhet was released on April 28, 2017, and Hour of Devastation was released on July 14, 2017. The eponymous plane has an ancient Egyptian theme, and features concepts like mummies and embalming. Amonkhet introduced three new mechanics: Exert: A keyword appearing on creatures. If a creature is exerted upon attacking or using an activated ability, it provides a bonus but does not untap during its controller's following turn, as seen on Glorybringer. Embalm: Paying the Embalm cost of a creature and exiling it from the graveyard creates a white Zombie creature token that is an exact copy of that creature, such as Angel of Sanctions. Aftermath: A new split card mechanic present on instants and sorceries. The first half is played as normal, but the Aftermath half can only be cast from a graveyard, such as Dusk and Dawn.
