What are sabotage cards? From the publisher:
A Sabotage card brings a new twist to the game. They allow you to throw the proverbial monkey wrench into your opponent's machine - making it malfunction is disastrous ways and all to your advantage. Put a stop to your opponent's pesky card-stealing contraptions, or power down his upgrades with sabotage cards like the Exothermic Reactor, Power Spike, or the Gremlin Sphere. You can really unleash some mayhem with these cards - and really ratchet up your own fun!
