Rules glossary
205.1 The type line is printed directly below the illustration. It contains the card’s card type(s). It also contains the card’s subtype(s) and supertype(s), if applicable.
- 205.1a Some effects set an object’s card type. In most such cases, the new card type(s) replaces any existing card types. However, an object with either the instant or sorcery card type retains that type. Counters, stickers, effects, and damage marked on the object remain with it, even if they are meaningless to the new card type. Similarly, when an effect sets one or more of an object’s subtypes, the new subtype(s) replaces any existing subtypes from the appropriate set (creature types, land types, artifact types, enchantment types, planeswalker types, or spell types). If an object’s card type is removed, the subtypes correlated with that card type will remain if they are also the subtypes of a card type the object currently has; otherwise, they are also removed for the entire time the object’s card type is removed. Removing an object’s subtype doesn’t affect its card types at all.
- 205.1b Some effects change an object’s card type, supertype, or subtype but specify that the object retains a prior card type, supertype, or subtype. In such cases, all the object’s prior card types, supertypes, and subtypes are retained. This rule applies to effects that use phrases such as “in addition to its other types” or that state that something is “still a [type, supertype, or subtype].” Some effects state that an object becomes an “artifact creature”; these effects also allow the object to retain all of its prior card types and subtypes. Some effects state that an object becomes a “[creature type or types] artifact creature”; these effects also allow the object to retain all of its prior card types and subtypes other than creature types, but replace any existing creature types. Example: An ability reads, “All lands are 1/1 creatures that are still lands.” The affected lands now have two card types: creature and land. If there were any lands that were also artifacts before the ability’s effect applied to them, those lands would become “artifact land creatures,” not just “creatures,” or “land creatures.” The effect allows them to retain both the artifact and land card types. In addition, each land affected by the ability retains any land types and supertypes it had before the ability took effect. Example: An ability reads, “All artifacts are 1/1 artifact creatures.” If a permanent is both an artifact and an enchantment, it will become an artifact enchantment creature.
