Beast-Warrior "Bujin" monsters you control cannot be destroyed by your opponent's card effects, except during the Battle Phase. Once per turn: You can send 1 "Bujin" monster from your hand or face-up field to the GY, then target 1 face-up card your opponent controls; negate its effects until the end of this turn. During your End Phase: You can send this face-up card from the field to the GY, then target 1 "Bujin" monster in your GY; Special Summon it.
