Oqirax, the Gravewaker

Flying, Deathtouch, Menace
As long as your devotion to black is less than
seven, Oqirax isn't a creature.
When Oqirax, the Gravewaker enters the
battlefield, all creatures you control get
+X/+X, where X is your devotion to black.
"You have trespassed for the last time, fools!
Leave now, or suffer the consequences."
