Flares are cards that cause various effects when played. Each flare has a corresponding alien named on it. During setup, each player gets two flares at random and chooses one of the two corresponding alien powers to use for the game. Then all flares that were dealt out during setup are shuffled into the deck before starting hands are dealt.
Each flare has two effects, labeled "Wild (If You Are Not the <alien name>)" and "Super (If You Are the <alien name>)" respectively. This means that if the player's alien does not match the alien named on the flare card, they can play the flare for its Wild effect, and if it does, they can play the flare for its Super effect. Note that if a player has lost their power or if their power is canceled, they may not use their Super flare but may use their flare's Wild effect. A flare returns to its player's hand after being played, and each player may only play one flare per encounter, even if the flare changes hands.
