Claim: Dark Elves is a new faction for the card game Claim and/or Claim2 with a unique ability, and this faction can be swapped for one of the existing factions in the base game to provide greater replayability. In Phase 2, if you collect at least one Dark Elf into your score pile in a trick, you must discard a non-Dark Elf card in your score pile from the game. (If you have only Dark Elf cards in your score pile, you do not have to discard a card. If you collect more than one Dark Elves in a trick, you still only discard one other faction card.) —description from the publisher
