Cultist-Spirit Cleric

This creature's power and toughness are each
equal to the number of Spirits you control.
They worshipped, so they said, the Great Old Ones
who lived ages before there were any men, and who
came to the young world out of the sky. Those Old
Ones were gone now, inside the earth and under the
sea; but their dead bodies had told their secrets in
dreams to the first men, who formed a cult which had
never died.
