Enchantment type

An enchantment type is any subtype used for the further classification of enchantment cards.
Unlike creature types, enchantment types don't have to appear on all enchantments. Instead, they have only been introduced for mechanical purposes.
==Rules==
==List of enchantment types==
===Aura===
Enchantments that possess the rules text "Enchant" are of the Aura subtype. These enchantments must be attached to an object specified by the Enchant ability, and exert an effect on that object.
An Aura's text box will specify what kind of permanents it can be attached to, reading "Enchant [type]." When an Aura spell is played, it must target an appropriate permanent, and when it resolves, it comes into play attached to (and no longer targeting) that permanent. If the permanent it is attached to leaves play at any time, becomes a type that the Aura cannot enchant, or gains protection against any of the Aura's characteristics, the Aura becomes unattached and will go to the graveyard.
Auras can be destroyed by cards with "destroy target aura" or "destroy target enchantment" as auras are just subtypes of enchantments.
Aura subtypes have no mechanical baggage and tend to merely be markers for other cards to refer to.
====Cartouche====
Cartouches are Auras that enchant creatures, giving them a boost that represents some kind of success or accomplishment. They give the creature they are enchanted to a boost of +1/+1 and a keyword, which is primary in that color. They also carry a secondary enter the battlefield effect, which also directly reflects the flavor of its color. Cartouches return their owner's Trials to their hand when they enter the battlefield.
====Curse====
Curses are Auras that enchant players. They were introduced in Innistrad and featured in the Innistrad block and Commander 2013. Although all Curses enchant players, not all enchantments with the "Enchant player" rules text are Curses. In fact, the ability has been featured on cards from previous expansion sets, such as <c>Psychic Possession</c> from Dissension.
====Pin====
Only appears on Test cards, represent lapel pins worn or given out at MagicCons.
====Role====
Roles are Aura tokens that enchant creatures, giving them different abilities related to the role a particular character have in a tale. Therefore, only one Role controlled by the same player can exist at the same time on a creature, so if a new Role is attached to that creature, the old one ceases to exist. However, one creature can have several Roles if each Role was created by a different player. 
====Rune====
Runes are Auras that can enchant any permanent, though as of now only provide an effect if attached to a creature or an equipment. All of them draw a card upon entry and bestow a keyword onto either the creature or the equipment's holder. Both cards that refer to Runes can search for them from the graveyard or library.
===Background===
Backgrounds are legendary enchantments that interact with Commanders in Commander games. They were introduced in Commander Legends: Battle for Baldur's Gate'.
===Case===
Cases are enchantments that were introduced in Murders at Karlov Manor. They represent mysteries to solve, and thus far all begin their name with "Case of the...", like classic detective stories. 
===Class===
Classes are enchantments with several effects. Similar to the level up mechanic they allow the player to unlock more abilities by paying costs.
===Entropy===
Only appears on test cards. Entropy is a predefined enchantment token with "Sacrifice this enchantment: Chaos ensues. Activate only as a sorcery." 
===Omenpath===
Only appears on test cards. Omenpaths are predefined enchantment tokens with "Sacrifice this enchantment: Planeswalk. Activate only as a sorcery." 
====Quest====
Only appears on test cards. Quests are enchantments that give you three tasks. You mark them as you finish each one. Once all of them are completed, you can sacrifice the card for a big effect.
===Realm===
Only appears on test cards. Similar to World Enchantments, but only affecting creatures that are hosted.
===Room===
Rooms are split card enchantments that represent the warped nature of Duskmourn. Each half of a room card can be cast individually, as per a split card. While on the battlefield, the other half can be unlocked by paying that half's mana cost as a special action.
===Saga===
Sagas are enchantments with several triggered effects that change with the passage of turns as each "chapter" unfolds. As the Saga enters the battlefield and then right after the player's draw step, they add a lore counter to the Saga, triggering the correspondent chapter ability, until the third chapter is reached and the Saga is sacrificed. Flavor-wise, each Saga is meant to tell the story of a key event from the past, like the rise of Benalia or the Mending.
===Shard===
Shards are predefined enchantment tokens with ", Sacrifice this enchantment: Scry 1, then draw a card." 
===Shrine===
Shrines are enchantments that possess an ability that is triggered at the beginning of its controller's upkeep. The effect is proportional to the number of Shrines that player controls. Shrines were introduced in Champions of Kamigawa, and all Shrines possess the legendary supertype.
