About Unstable Unicorns, from BoardGameGeek:

Build a Unicorn Army. Betray your friends. Unicorns are your friends now. Unstable Unicorns is a strategic card game about everyone's two favorite things: Destruction and Unicorns! Players draw and discard cards in a race to build an army of 7 unicorns. Sound easy? Not so fast. Someone could have a Neigh Card (Get it? Neigh?) or Downgrade cards to stop you in your tracks. But you can do the same to them. The first person to complete their Unicorn Army shall hereafter be known as The Righteous Ruler of All Things Magical. -description from the publisher
