You are the director of the Observatory. With your telescopes aimed at the stars, planets and nebulas of the Oniverse, you are ready to launch daring spaceships into the skies. Stellarion, the sixth entry in the Oniverse series, is a deck management game: all the cards you need are split into 8 decks, and you know the contents of each one. You'll need to manage all these resources to ensure you have the right cards available at the right time.
