In the instance of the activation of SCP-3526 see addendum 372-N.
Description: SCP-3526 is a normal looking deck of 52 standard issue playing cards. No anomalous properties are recorded until SCP-3526 is used to play and type of card game. Upon the activation of SCP-3526 the air within a 10 kilometer radius will start to vibrate as if it where statically charged. When this happens every living organism within that 10 kilometer radius will dissolve into little more than dust. You can touch the cards with no negative effects from the cards themselves, it only activates when they are used on a game.
