Council of Elrond

Ok, i've been working on the jpgs yesterday, and i have the following questions:

great goblin: can he be keyed to like the normal one???

balance between powers: we make it a unique card or just "cannot be duplicated"???

best!

Re Great Goblin, I don't see any immediate reason why the dark-hold should be removed.

Re BBP, my immediate thought would be to make this card like Twilight - a hazard event that can be played as a resource (by both minion and hero). You'd need 'cannot be duplicated' I think too.
