got the prize kit and inside the little league booklet it mentions the elder sign and what it is. the voting forms give the option of agency, miskatonic, syndicate, or mythos (which makes it so the card 'doesn't see the light of day, wont be printed??)
well here is the card
The Elder Sign (support)
Disrupt: When a card is played from a player's hand, remove Elder Sign from the game to cancel all effects of playing that card, and remove it from the game. (Cards removed from the game no longer interact with any game effects.)
