Choose a card in your opponent's scrap pile and put it on top of their deck.
Some cards refer to Autobots or Decepticons. How do I know which characters are Autobots?
Autobots have a red frame and the Autobot insignia in the lower right corner. Decepticons have a purple frame and the Decepticon insignia in the lower right corner. A few characters have "Autobot" or "Decepticon" in their names, although these aren’t the only Autobots and Decepticons.
