R'lyeh

{t} Add {u/b} to your mana pool
When R'lyeh enters the battlefield, search your library and graveyard for a card named Cthulhu
and put it into your hand.
A coast-line of mingled mud, ooze, and weedy
Cyclopean masonry which can be nothing less than the tangible substance of earth's supreme terror, the
nightmare corpse-city of R'lyeh, that was built in measureless aeons behind history by the vast,
loathsome shapes that seeped down from the dark stars.
