Host is a supertype with no inherent functionality. Instead, it serves as an identifying characteristic, and is closely tied to cards with augment.[2][3][4] Host appears on creatures in Unstable and Unsanctioned.[4] All host creatures have an ETB ability which becomes a repeatable triggered ability when the host is combined with an augment.For the test card keyword action, see Host (keyword action).Host creatures always have a card name in two parts divided by a fissure, a metal bar running vertically through their art and a text box split in two unequal parts.[2]Unlike other supertypes, like basic or world, but similar to snow, host does nothing other than to identify host creatures.
