Mindbug: Beyond Eternity

From Nerdlab Games:

In this standalone expansion, Mindbug: Beyond Eternity introduces the Boost ability where you can use cards from your graveyard to give your creatures a +1 boost in power. Also cards can have effects when in your graveyard, such as making them stronger.

In Mindbug, you summon hybrid creatures and send them to battle against your opponent. But be careful: your opponent may use one of their Mindbugs to take control of it.

Outwit your opponent in a fascinating tactical duel in which having the best cards and playing them at the wrong time can be deadly for yourself.

Mindbug combines the accessibility and fairness of a simple card game with the strategic depth of a complex Strategy Card Game. The result is a skill-based dueling card game that feels utterly different from all the other card games you have played before.

This expansion can be played on its own, or mixed with Mindbug: First Contact or Mindbug: Beyond Evolution.
