Planeswalkers have their own unique set of subtypes; these subtypes are called planeswalker types. The planeswalker types are Ajani, Bolas, Chandra, Domri, Elspeth, Garruk, Gideon, Jace, Karn, Koth, Liliana, Nissa, Ral, Sarkhan, Sorin, Tamiyo, Tezzeret, Tibalt, Venser, and Vraska. If a player controls two or more planeswalkers that share a planeswalker type, that player chooses one of them, and the rest are put into their owners' graveyards. This "planeswalker uniqueness rule" is a state-based action. See rule 704.

Previously, a spell or ability that affected cards from a particular set checked for that set's expansion symbol. These cards have received errata in the Oracle card reference to say they affect cards "originally printed" in a particular set. See rule 700.5 for details.

An ability word appears in italics at the beginning of some abilities. Ability words are similar to keywords in that they tie together cards that have similar functionality, but they have no special rules meaning and no individual entries in the Comprehensive Rules. The ability words are battalion, bloodrush, channel, chroma, domain, fateful hour, grandeur, hellbent, imprint, join forces, kinship, landfall, metalcraft, morbid, radiance, sweep, and threshold.

Some artifacts have the subtype "Fortification." A Fortification can be attached to a land. It can't legally be attached to an object that isn't a land. Fortification's analog to the equip keyword ability is the fortify keyword ability. Rules 301.5a-d apply to Fortifications in relation to lands just as they apply to Equipment in relation to creatures, with one clarification relating to rule 301.5c: a Fortification that's also a creature (not a land) can't fortify a land. (See rule 702.66, "Fortify.")

If an effect attempts to put a non-Aura permanent onto the battlefield attached to a creature, that permanent enters the battlefield unattached.

If an effect attempts to put a permanent that isn't an Aura, Equipment, or Fortification onto the battlefield attached to an object or player, it enters the battlefield unattached.

If a non-Aura permanent has an ability that refers to the "enchanted [object or player]," that phrase doesn't refer to any object or player.

An ability of a permanent that refers to the "enchanted [object or player]" refers to whatever object or player that permanent is attached to, even if the permanent with the ability isn't an Aura.

If an effect sets a land's subtype to one or more of the basic land types, the land no longer has its old land type. It loses all abilities generated from its rules text and its old land types, and it gains the appropriate mana ability for each new basic land type. Note that this doesn't remove any abilities that were granted to the land by other effects. Setting a land's subtype doesn't add or remove any card types (such as creature) or supertypes (such as basic, legendary, and snow) the land may have. If a land gains one or more land types in addition to its own, it keeps its land types and rules text, and it gains the new land types and mana abilities.

If an effect sets a land's subtype to one or more of the basic land types, the land no longer has its old land type. It loses all abilities generated from its rules text, its old land types, and any copy effects affecting that land, and it gains the appropriate mana ability for each new basic land type. Note that this doesn't remove any abilities that were granted to the land by other effects. Setting a land's subtype doesn't add or remove any card types (such as creature) or supertypes (such as basic, legendary, and snow) the land may have.
