i'll just leave this here. http://bulbapedia.bulbagarden.net/wiki/Feint_%28move%29
Feint can now inflict damage even if the target has not used Protect or Detect and its power has changed from 50 to 30.
Despite being an increased priority move, Feint will lift the effects of Wide Guard and Quick Guard for the remainder of the turn only if they are used on an opposing team. Feint can still break an ally's Protect or Detect, but cannot break a Pokémon's Endure.
