Unstable (Magic: The Gathering)
Unstable is an official parody expansion set to the collectible card game Magic: The Gathering that was released on December 8, 2017. It is the third set of its kind, featuring silver borders, following in the tradition of 1998's Unglued and 2004's Unhinged. Flavor and background Unstable takes place on Bablovia, a steampunk-inspired plane. It features five main factions, one for each allied color pairing: The Order of the Widget (white-blue), the Agents of S.N.E.A.K. (blue-black), the League of Dastardly Doom (black-red), the Goblin Explosioneers (red-green) and the Crossbreed Labs (green-white). Mechanics Unstable features interactions with "Host" creatures via the "Augment" mechanic. Certain creatures have the supertype "Host" and feature an effect that triggers when they enter the battlefield. Other creatures have the "Augment" ability and can only be played on top of a Host creature. When this is done, the Augment creature replaces the "when this creature enters the battlefield" trigger with a different trigger, making the Host's mechanic repeatable in some way. The art and card frames for Host and Augment creatures are designed such that the Augment creature can visually replace the front half of the Host creature, turning the composite creature into a hybrid.
