Entwine is a static ability that functions while the spell is on the stack. “Entwine [cost]” means “You may choose to use all modes of this spell instead of just one. If you do, you pay an additional [cost].” When the spell resolves, if the entwine cost was paid, follow the text of each of the modes in the order they’re written on the card. See rule 502.32, “Entwine.”

Epic represents both a static ability and a delayed triggered ability. “Epic” means, “For the rest of the game, you can’t play spells,” and “At the beginning of each of your upkeeps, copy this spell except for its epic ability. If the spell has any targets, you may choose new targets for the copy.” See rule 502.44, “Epic.”

Equip is an activated ability. “Equip [cost]” means “[Cost]: Attach this Equipment to target creature you control. Play this ability only any time you could play a sorcery.” See rule 502.33, “Equip,” and rule 212.2, “Artifacts.”

Some artifacts have the subtype “Equipment.” These artifacts can be attached to (can “equip”) creatures. They can’t equip objects that aren’t creatures. An Equipment is played and comes into play just like any other artifact. Equipment doesn’t come into play equipping a creature. The equip keyword ability moves the Equipment onto a creature you control. (See rule 502.33, “Equip.”) The creature an Equipment is attached to is called “equipped.” The Equipment is attached to, or “equips,” that creature.

An Equipment that’s also a creature or an Equipment that loses the subtype “Equipment” can’t equip a creature. An Equipment can’t equip itself. An Equipment that equips an illegal or nonexistent permanent becomes unattached from that permanent, but remains in play. (This is a state-based effect. See rule 420.)

Evasion abilities restrict what creatures can block an attacking creature. These are static abilities that modify the declare blockers step of the combat phase. See rule 501, “Evasion Abilities.”

Anything that happens in a game is an event. Multiple events may take place during the resolution of a spell or ability. The text of triggered abilities and replacement effects defines the event they’re looking for. One “happening” may be treated as a single event by one ability and as multiple events by another.

Example: If an attacking creature is blocked by two defending creatures, this is one event for a triggered ability that reads “Whenever [name] becomes blocked” but two events for a triggered ability that reads “Whenever [name] becomes blocked by a creature.”

A spell or ability may instruct two players to exchange something (for example, life totals or control of two permanents) as part of its resolution. When such a spell or ability resolves, if it can’t exchange the chosen things, it has no effect on them.

Example: If a spell attempts to exchange control of two target creatures but one of those creatures is destroyed before the spell resolves, the spell does nothing to the other creature. Or if a spell attempts to exchange control of two target creatures but both of those creatures are controlled by the same player, the spell does nothing to the two creatures.

When control of two permanents is exchanged, each player simultaneously gains control of the permanent that was controlled by the other player.

When life totals are exchanged, each player gains or loses the amount of life necessary to equal the other player’s previous life total. Replacement effects may modify these gains and losses, and triggered abilities may trigger on them.

Some spells or abilities may instruct a player to exchange cards in one zone with cards in a different zone (for example, cards removed from the game and cards in a player’s hand). These spells and abilities work the same as other “exchange” spells and abilities, except they can exchange the cards only if all the cards are owned by the same player.

If a spell or ability instructs a player to simply exchange two zones, and one of the zones is empty, the cards in the zones are still exchanged.

The small icon normally printed below the right edge of the illustration on a Magic card is the expansion symbol. It indicates the set in which the card was published. Cards reprinted in a core set or another expansion receive its expansion symbol. Spells and abilities that affect cards from a particular expansion only affect cards with that set’s expansion symbol. The first five editions of the core set had no expansion symbol. See rule 206, “Expansion Symbol. Visit the products section of www.magicthegathering.com for the full list of expansions and expansion symbols (www.wizards.com/default.asp?x=magic/products/cardsets).

Players may include cards from any printing in their constructed decks if those cards appear in sets allowed in that format (or allowed by the Magic Floor Rules). See the Magic Floor Rules for the current definitions of the constructed formats (www.wizards.com/default.asp?x=dci/doccenter/home).

Some spells and abilities can give a player extra turns. They do this by adding the turns directly after the current turn. If a player gets multiple extra turns or if multiple players get extra turns during a single turn, the extra turns are added one at a time. The most recently created turn will be taken first. See rule 300.6.

The Grand Melee multiplayer variant has a special rule to handle when extra turns are taken: If a player would take an extra turn after the current turn and it’s not currently that player’s turn, that player instead takes the extra turn immediately before his or her next turn. See rule 608, “Grand Melee Variant.”

Face-down spells on the stack, face-down permanents in play, and face-down cards in the phased-out zone have no characteristics other than those listed by the ability or rules that allowed the card, spell, or permanent to be turned face down. Any listed characteristics are the copiable values of that object’s characteristics.

At any time, you may look at a face-down spell you control on the stack, a face-down permanent you control, or a face-down card in the phased-out zone you controlled when it phased out. You can’t look at face-down cards in any other zone, face-down spells or permanents controlled by another player, or face-down cards in the phased-out zone last controlled by another player.

The ability or rules that allowed a permanent to be turned face down may also allow the permanent’s controller to turn it face up. Spells normally can’t be turned face up.

If you control multiple face-down spells on the stack or face-down permanents in play, you must ensure at all times that your face-down spells and permanents can be easily differentiated from each other.

See rule 504, “Face-Down Spells and Permanents,” and rule 502.26, “Morph.”
