When Pigs Fly is an ability exclusively used by Warpig. This ability gives a short boost of attack plus 2 if the Warpig is Flying, by any means, including Levitate and Ring of Flight. The boost only starts at the start of the attack phase and is removed before the battle cycle is ended, so that it cannot prevent any Sap. The boosted attack is only available in the attack phase, so that it will not be sapped, being treated independant of the other bonuses and base attack.
