I am fully aware that Feint would normally have no effect on Aegislash. This is specifically for Mega Pinsir, whose Aerilate ability makes Feint a Flying move and thus it can hit Aegislash.
Feint, when used, breaks the opponent's Protect / Detect / King's Shield / Spiky Shield. When a contact move is used on King's Shield, the opponent's Attack stat is lowered by -2 stages. I am pretty sure that Feint is a contact move.
Will Mega Pinsir receive the Attack drop? Or will it not activate be activated because Feint broke King's Shield?
