The goal of Unstable Unicorns is to be the first person to collect 7 Unicorns in your play area, also known as your Stable. You do this by gathering up your own Unicorn army and using a combination of their magical powers and Magic, Instant, Upgrade, and Downgrade cards to hinder the other players’ progress and destroy their Unicorns instead. But beware — each player has all of these tools at their disposal as well, and you may just find your plans foiled by a well-played “Neigh!” card.
