In game terms, the Paramedics card is magical.
The shield symbol in the upper right corner identifies it as a defense, which can be used to counteract an attack card (they have a crosshairs symbol) against a player’s contacts or groups.
Also, the lack of category symbols in the upper left means Paramedics can be used to negate an attack from any category.
Think about that for a second. Assassin’s bullet? Call the paramedics. Drone strike? Paramedics. Cyanide poisoning? Zombie attack? Demonic possession? That’s right: call the paramedics—you’ll be fine.
