Cthulhu, Dreaming

When Cthulhu, Dreaming, is in your hand, you
may reveal it and sacrifice any number of Islands
and Swamps. For each land sacrificed in this
way, add {c} to your mana pool.
This spell can't be countered.
At the start of your upkeep, all players lose the
game.
"...with strange aeons even death may die."
