Part 35 (1/2)
Type
The word ”type” has two meanings: 1. A card's type (and subtype and supertype, if applicable) is printed directly below the ill.u.s.tration on the card, on its type line. Cards, tokens, permanents, and spells all have types. Abilities don't have types. See rule 205, ”Type Line,” and rule 212, ”Type, Supertype, and Subtype.”
When an effect changes an object's type, the new type replaces all previous types. If the effect is adding a type, or allowing an object to retain its types, it will say so. See rule 212.1c.
2. The ”type” of mana is its color, or lack thereof (for colorless mana). See also Mana.
Type Line
The type (and subtype and supertype, if applicable) of a card is printed directly below the ill.u.s.tration. See rule 205, ”Type Line,” and rule 212, ”Type, Supertype, and Subtype.”
Type-Changing Effect
A type-changing effect is an effect that changes the type of an object. It's generated by a type-changing ability. See rule 418.5a.
Unattach
An Aura or Equipment becomes unattached if it was attached to a permanent and then is not. If an Aura or Equipment leaves play while attached to a permanent, it becomes unattached. If a permanent leaves play (unless it phases out) while an Aura or Equipment is attached to it, the Aura or Equipment becomes unattached.
Unblockable
If an attacking creature ”is unblockable,” no creature can legally block it. Spells or abilities may still cause it to become blocked.
Unblocked
A creature is unblocked if it's attacking and no creature blocked it during the declare blockers step of the current combat phase. It remains an unblocked creature until an effect causes it to become blocked, it's removed from combat, it stops being a creature, its controller changes, or the combat phase ends. Unblocked creatures don't exist outside of the combat phase or before the declare blockers step. See rule 309, ”Declare Blockers Step.”
Universal Tournament Rules
The DCI Universal Tournament Rules (/default.asp?x=dci/doccenter/home) cover tournament play for all DCI-sanctioned games, including the Magic game.
Unless
Some cards use the phrase ”[Do something] unless you [do something else].” This means the same thing as ”You may [do something else]. If you don't, [do something].”
