Yawgmoth, God of Phyrexia

Indestructible
As long as your devotion to Phyrexia is less than
7, Yawgmoth isn't a creature. (Each {p/c} of any color in the mana costs of permanents you control counts toward your devotion to Phyrexia.)
{1}{p/b}{p/b}: Target creature gets -5/-5 until end of turn.
{2}{b}{b}: Destroy all creatures. They can't be regenerated.
