After each round, you will automatically regain 15 energy. Each card shows valuable information. The highlighted squares at the top right of each card show which squares will be affected by its action. In versus mode, Player 1 uses the keyboard and goes first. Player 2 uses the mouse, and plays normally. Cards are hidden during the selection phase.
