NIGHTMARE - Fan Designed Cosmic Expansion Set

You have the power to Recur. As a main player, after you lose an encounter, you may use this power to place your encounter card face-up next to your opponent's alien sheet as a “nightmare” instead of discarding it. The nightmare is not part of that player's hand.

Any main player who has a nightmare next to his or her sheet must play it as his or her encounter card, if possible. If that player loses an encounter or fails to deal while playing a nightmare, the nightmare transfers to his or her opponent's alien sheet instead of being discarded, unless that opponent is you. Otherwise the nightmare is discarded like any other encounter card.

When the offense has a nightmare next to his or her sheet and you are the defense, before encounter cards are selected, the nightmare is discarded.

SUPER (IF YOU ARE THE NIGHTMARE)

History
Throughout the countless incursions where entire colonies and worlds have been mercilessly laid waste, the begrudged revenants of the forgotten dead merge behind the veil of space. This avatar horrifically returns the violence and shattered dreams the cosmos has collectively inflicted upon it back into the living plane as a true nightmare.

This is the final version, I did all the edits that were mentioned except changing the Super, because without this Super Nightmare still has to lose encounters to have a power, but with it he has a power when winning also. - Christopher Oliveira
