The Slaughter

Patron - The Slaughter can be your commander.
If it is, creatures you control are goaded and attack
a random opponent if able. At the end of combat,
each creature you control deals damage to you
equal to its power.
Whenever one or more creatures attacks, its
controller draws a card and loses 1 life.
{3}{w}{g}{r}: Each creature target opponent controls
is goaded until the start of your next turn.
