Attach

To attach an Aura or Equipment to a permanent means to take it from where it currently is and put it onto that permanent. If the Aura or Equipment no longer exists or the object it will move onto is no longer in the correct zone when the effect would attach it, nothing happens. Similarly, an Aura or Equipment can't be attached to a permanent it couldn't enchant or equip. The Aura or Equipment stays where it is, with one exception: If an Aura is coming into play from the stack and there is no legal permanent for it to enchant, the Aura is put into its owner's graveyard instead of coming into play. If an effect tries to attach an Aura or Equipment to the permanent it's already attached to, the effect does nothing. Attaching an Aura in play to a different permanent causes the Aura to receive a new timestamp. Nothing else about the Aura changes. The Aura never left play, so no comes-into-play or leaves-play triggered abilities will trigger. If an ability of the moved Aura affecting "enchanted [permanent]" was on the stack when the Aura moved, it will affect the new enchanted permanent when it resolves, not the old one. The same is true for moved Equipment.

Attach

To attach an Aura, Equipment, or Fortification to an object means to take it from where it currently is and put it onto that object. If the Aura, Equipment, or Fortification no longer exists or the object it will move onto is no longer in the correct zone when the effect would attach it, nothing happens. Similarly, an Aura, Equipment, or Fortification can't be attached to an object it couldn't enchant, equip, or fortify, respectively. The Aura, Equipment, or Fortification stays where it is, with two exceptions: If an Aura would phase in but can no longer enchant the object it was attached to, it phases in and is then put into its owner's graveyard as a state-based effect; and if an Aura is coming into play from the stack and there is no legal object for it to enchant, the Aura is put into its owner's graveyard instead of coming into play. If an effect tries to attach an Aura, Equipment, or Fortification to the object it's already attached to, the effect does nothing. Attaching an Aura in play to a different object causes the Aura to receive a new timestamp. Nothing else about the Aura changes. The Aura never left play, so no comes-into-play or leaves-play triggered abilities will trigger. If an ability of the moved Aura affecting "enchanted [object]" was on the stack when the Aura moved, it will affect the new enchanted object when it resolves, not the old one. The same is true for moved Equipment and Fortifications.
