Fervor

{2}{R} · Enchantment

Creatures you control have haste. (They can attack and {T} as soon as they come under your control.)

Motor: se resuelve a mano

Rulings (1)

If an attacking creature loses haste, perhaps because Fervor leaves the battlefield after attackers have been declared, it won't be removed from combat.
