Protector of Lorien

By Tracker1, in Rules questions & answers

If I have attached a copy of this card to two or more heroes, when I discard a card will all the heroes with the card attached get +1 willpower?

No. When you trigger an ability on a copy of PoL, you discard a card as the cost. You cannot discard a card as to paying the cost of two (or more) copies of PoL.
