The goal of Unstable Unicorns is to be the first player to collect 7 unicorns in your stable. Do this by gathering up your own Unicorn army and using a combination of their unique and wonderful powers, Magic cards, Instant cards, Upgrade cards, and Downgrade cards to hinder the other players' progress and destroy the Unicorns collected in their own stables.

But beware... each player has all of these tools at their disposal too, and you might just find your plans foiled by a well-played "Neigh!" card.
