I have a Tyrion Lannister in play.
I use Hear Me Roar! and dupe Tyrion with another copy in my hand.
What happens when the delayed effect resolves?
a. The Dupe is discarded because that was the card put into play. Tyrion stays.
or
b.All Tyrion's are discarded because of "(cannot be saved)"
Or if both are incorrect, what would happen?
