Rulings
- Show the card to your opponent.
- If Imperial Order & Necrovalley are both applying, and An Owl of Luck is flipped, you add the card to your hand because Necrovalley is face-up on the field, even though its effect is negated.
- You select the card for this effect when the effect resolves, not when it activates.
