|Power of duality|
|Plays 2 encounter cards|
As a main player or ally, after encounter cards are revealed, if you have an attack card that is identical to one of the revealed cards, you may discard it, either adding or subtracting its value from the total of the player who played the matching card.
You may discard both your encounter card and your extra card after they are revealed in an encounter.
Deuce is an alien with the power to play two encounter cards together instead of one. If it plays two attacks, it adds them together; if it plays at least one , it uses only the and ignores its other card. At the end of the encounter, it discards only one of its played cards (the if it played one, or the higher attack card if it did not) and must return the other card to its hand. In addition, when checking to see if it needs a new hand, it does so if it has one or fewer encounter cards rather than none.
