A deck of 108 "Tactical Playing Cards" (or T-cards) to use when playing an ASL scenario. Each player receives at game start a number of cards from the deck and may play them whenever he sees fit during a scenario. Each card has an effect printed on it, just apply what is written on the card and discard the card. The total number of cards in the deck is sufficiently large to ensure that no hand will be similar to another. The rules underpinning T-cards' use are as concise as possible.
