it will affect the new enchanted permanent when it resolves, not the old one. The same is true for moved Equipment.
A creature attacks when it’s declared as an attacker during the combat phase. (See rule 308, “Declare Attackers Step.”) Playing a spell or ability (even during the combat phase) is never considered to be an attack.
A creature is attacking alone when it’s the only creature declared as an attacker in a given combat phase. See rule 306.4.
Some multiplayer games use the optional “attack left” rules. If the attack left option is used, a player can attack only an opponent seated immediately to his or her left. If a player’s nearest opponent to the left is more than one seat away, the player can’t attack. See rule 604, “Attack Left and Attack Right Options.”
Some multiplayer games allow the active player to attack multiple opponents. Each of the attacked players is a defending player. Each defending player can block only the creatures attacking him or her. See rule 602, “Attack Multiple Players Option.”
Some multiplayer games use the optional “attack right” rules. If the attack right option is used, a player can attack only an opponent seated immediately to his or her right. If a player’s nearest opponent to the right is more than one seat away, the player can’t attack. See rule 604, “Attack Left and Attack Right Options.”
A creature becomes an attacking creature when
An ability that triggers when a creature “attacks and isn’t blocked” triggers when the creature becomes an unblocked attacking creature. See rule 309.2f.
Some enchantments have the subtype “Aura.” An Aura spell requires a target whose properties are indicated by its enchant keyword ability. An Aura permanent comes into play attached to the permanent or player the spell targeted. See rule 212.4, “Enchantments,” and rule 502.45, “Enchant.”
An Aura can enchant only a permanent or player whose properties are indicated by its enchant keyword ability. An Aura attached to an illegal permanent or not attached to a permanent is put into its owner’s graveyard. (This is a state-based effect. See rule 420.)
Banding is a static ability that modifies the rules for declaring attackers and assigning combat damage. “Bands with other” is a specialized version of the ability. See rule 502.10, “Banding,” and rule 502.11, “Bands with Other.”
Basic is a supertype. Any land with the supertype basic is a basic land. Any land without that supertype is a nonbasic land. See rule 205.4, “Supertypes.”
There are five basic land types: Plains, Island, Swamp, Mountain, and Forest. Every basic land type has a mana ability associated with it. (See rule 212.6, “Lands.”)
Some trigger events use the word “becomes” (for example, “becomes tapped” or “becomes blocked”). These trigger only at the time the named event happens-they don’t trigger if that state already exists or retrigger if it persists. For example, “becomes tapped” triggers only when a permanent’s status changes from untapped to tapped.
The beginning of combat step is the first step of the combat phase. A player may play spells and abilities during this step whenever he or she has priority. See rule 307, “Beginning of Combat Step.”
The beginning phase is the first phase of the turn. It has three steps: untap, upkeep, and draw. See rule 301, “Beginning Phase.”
A creature blocks when it’s declared as a blocker during the combat phase. See rule 309, “Declare Blockers Step.”
A creature is blocking alone when it’s the sole creature controlled by the defending player declared as a blocker in a given combat phase. See rule 306.4.
An attacking creature becomes a blocked creature when another creature blocks it or an effect causes it to
