"Discard 2 cards from your hand. Select 1 face-up monster and flip it face-down, but do not change its battle position."
Getting official rulings on this card is about as easy as walking on water. So let's just get to the point- can Darkness Approaches be used to activate a flip effect the same turn a flip effect monster is summoned or set?
Yes, it's the only card that allows what would otherwise be known as rulings blasphemy in the game- that is the condition of a face-down attack position monster. But along with an utter slap to the face of judges, there are no rulings save for the opinions of so-called "experts" in rulings (whom by the way, should concede to seniority and experience).
The primary argument against Darkness Approaches is that a monster cannot be flip summoned during the same turn it is set. However, a flip summon is equivalent to a manual change in battle position, as recognized by the acceptance of the ruling that a player cannot manually change a flip summoned monster during the same turn and a monster's battle position cannot be changed manually if it has already been changed manually, attacked, or is summoned during the same turn.
Ergo, the reason why you can't flip summon a monster the same turn it has been set on the field is because you cannot manually change the battle position of a monster the same turn it is set.
Darkness Approaches, therefore, does not violate this, because, even if a monster is summoned in attack position then flipped face-down by Darkness Approaches, it's battle position remains the same.
Does anyone have some sound logic to help explain what you can legally do with a face-down attack position monster?
