Gods are a creature type reserved for divine beings from across Magic's settings and Universes Beyond worlds. Their mechanics vary considerably, although Gods are often difficult to remove and provide powerful abilities worthy of their divine status.
Theros Gods such as Thassa, God of the Sea use devotion to determine when they become creatures, while Amonkhet's Gods have their own methods of returning or remaining relevant after death. Esika, God of the Tree provides a particularly colorful celestial build-around.
