Host

Host is a supertype with no inherent functionality. Instead, it serves as an identifying characteristic, and is closely tied to cards with augment.

Description
Host appears on creatures in Unstable and Unsanctioned. All host creatures have an ETB ability which becomes a repeatable triggered ability when the host is combined with an augment. The exact condition for the triggered ability depends on the augment.

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.

Unlike other supertypes, like basic or world, but similar to snow, host does nothing other than to identify host creatures. Instead, various effects reference host creatures, mainly the augment ability.
