Irmagul, Crimson Conjurant

When Irmagul, Crimson Conjurant enters the battlefield, each player sacrifices creatures they control whose total converted mana costs equal 6 or more. Then, for each player who sacrificed three or more creatures, create a 6/6 black and red Blood Avatar creature token.
If Irmagul is sacrificed by this ability, you lose the game.
