Whenever Hammer of Nazahn or another Equipment you control enters, you may attach that Equipment to target creature you control.
Equipped creature gets +2/+0 and has indestructible (Effects that say "destroy" don't destroy that permanent. An indestructible creature can't be destroyed by damage.).
Equip (: Attach to target creature you control. Equip only as a sorcery. This card enters unattached and stays on the battlefield if the creature leaves.)
