Hey all,

Just wondering with Rhaegal from the core set (http://www.cardgamedb.com/index.php/GoTCards.html/_/core-set/Rhaegal-Core) I was wondering when you attach the other copy, does your original Rhaegal become an 8 strength character? Also say before I pay for the duplicate and I lose stealth, do I gain it back when I attach the duplicate? Thanks for the help.

No on both counts, attaching a duplicate to a card only protects against the card being killed or discarded or returned to hand/deck

Rulebook page 19 has more detail but this part deals with what a duplicate protects against:

If one of your unique cards is about to be killed
discarded from play, or returned to your hand
or deck, as a triggered “Response:” effect (see
later), you may discard an attached duplicate to
save the unique card from being killed, discard
ed, or returned to your hand or deck.

Also you don't pay to attach the duplicate, it is attached during your marshalling phase for 0 gold cost.

Ahh ok. Thanks for the clarifaction Darksbane!

Although you do have to pay 1 Gold to use his hability...
