Its sometimes useful to have an extra copy of certain uniques within your deck, to increase the odds of drawing that card, which can be pivotal to success depending on the deck. However, once you have the card in play, extra copies lose value quickly. I find sometimes having an extra copy of a unique ally can be useful if they have very low HP, or if i want to sacrifice them for gain, and just play them again next round, but this usually is not the case. So what are the options for excess uniques? Help me build a list:
Discard with Eowyn for questing bonus
Use for the Long Dark's location tests
Discard with Daeron's Runes for additional card draw
Discard with Protector of Lorien for +1 Will or +1 Defense
Save as a throw away cards for certain treachery, locations, or enemies that force discard.
Place back into deck and force lower into deck with Gildor
Use to damage enemies with Taking initiative in conjuction with Gildor.
