Silidar, The Wretched

Flying, Indestructible
{b}{b}{b}{b}: create 4 1/1 raven creature tokens.
{10}, {ut}: you draw 7 cards, gain 7 life, and return a creature from your graveyard to the battlefield,
each opponent discards 7 cards, sacrifices 7
permanents and looses 7 life.
No one survives the gaze of Silidar.
