Rise From R'lyeh

Mill seven cards, then draw seven cards,
then discard seven cards
Search your library or graveyard for a card called Cthulhu, Sleeper of R'lyeh, and put
that card into your hand
"The Thing of the idols, the green, sticky spawn
of the stars, had awakened to claim it's own"
-H.P. Lovecraft in Call of Cthulhu
