(I feel like this might have been discussed to a certain extent somewhere already, but I can't find it...)
Several of the Grey Havens events have effects that depend on the # of copies in your discard pile. If 1x Skyward Volley is in your discard pile, and you play it via the Book of Eldacar, do you:
- Resolve the main effect twice because you do have a copy of Skyward Volley in the discard pile (itself), or
- Resolve it only once because that copy is considered to be in your hand and NOT the discard pile anymore...?
