Guise of Fire

The controller of the enchanted creature still decides which player or planeswalker the creature attacks.

If, during its controller’s declare attackers step, the enchanted creature is tapped, is affected by a spell or ability that says it can’t attack, or hasn’t been under that player’s control continuously since the turn began (and doesn’t have haste), then it doesn’t attack. If there’s a cost associated with having a creature attack, the player isn’t forced to pay that cost, so it doesn’t have to attack in that case either.
