Call of Cthulhu Living Card Game : Search for the Silver Key

From the Publisher's website:-

Search for the Silver Key is the fourth Asylum Pack in the Dreamlands expansion for the Call of Cthulhu Living Card Game. The search for Twila-Katherine Price leads to an ancient artifact that can open the way to the Dreamlands.

Search for the Silver Key contains 20 different never-before-seen cards based on the dark mythos of master horror writer H.P. Lovecraft, designed to augment existing decks and add variety to the Call of Cthulhu metagame.

This is not a stand-alone deck; you must have additional Call of Cthulhu LCG cards to play.
