Supertype

A supertype is a characteristic of a Magic card and a word that may appear on a card's type line just before its card types:

Description
Each supertype has rules attached to them, for example:
 * More than four copies of a basic land can be included in a deck with no upper limit
 * State-based actions dictate what happens if multiple legendary permanents with the same name are simultaneously on the battlefield under a single player's control
 * The same is true for if multiple world permanents are simultaneously on the battlefield regardless of name or who controls those permanents
 * Some cards also refer to supertypes by prefixing them with "non", which means all cards that do not have that supertype

Official supertypes

 * Basic
 * Legendary
 * Ongoing (schemes only)
 * Snow
 * World

Non-official supertypes

 * Elite (Face the Hydra Challenge Deck only)
 * Host (silver-bordered only)

Nonstandard cards
Some cards printed for special purposes are not supported in the Comprehensive Rules.
 * Notable in this case is the Heroes of the Realm card Optimus Prime, Inspiring Leader, which has the supertype Autobot.
