Lost in the Dark
A Shadow in the East #65 (x1)

It's nearly impossible to find your way through this maze of dark tunnels.

When Revealed: Each player places the top 10 cards of his deck facedown under his threat dial (without looking at them). When this stage is defeated, each player shuffles all cards under his threat dial back into his deck.

Forced: After a player raises his threat by any amount, he discards the top card from under his threat dial.
