Enchantment, 2R (3)
Rare
Creatures you control have haste. (They can attack and {T} as soon as they come under your control.)
The intensity of their glare was soon surpassed by the intensity of their attack.
Illus. Wayne England
7/1/2012: If an attacking creature loses haste, perhaps because Fervor leaves the battlefield after attackers have been declared, it won't be removed from combat.
