Predatory Impetus

Only one creature is required to block the enchanted creature. Other creatures may also block it and are free to block other creatures or not block at all.

If each creature the defending player controls can't block for any reason (such as being tapped), then the enchanted creature isn't blocked. If there's a cost associated with blocking the enchanted creature, the defending player isn't forced to pay that cost, so it doesn't have to be blocked in that case either.

If the creature doesn't meet any of the above exceptions and can attack, it must attack a player other than the controller of the spell or ability that goaded it if able. If the creature can't attack any of those players but could otherwise attack, it must attack a planeswalker an opponent controls, a battle an opponent controls, or a player who goaded it.
