In Sleeper Cells players take turns drawing and playing cards to lead attacks against their opponent. The game ends when a player runs out of life. Outwit your opponent in a tactical duel where playing the strongest cards at the wrong time can be just as deadly for you as for your opponent. Each turn consists of 3 actions. You may draw cards play, flip cards or attack with cards all with the intent of overwhelming your opponent and destroying them. —description from the designer
