Nezarec, Final God of Pain

Trample, Menace 3, Intimidate
Whenever a player loses life, Regenerate Nezarec.
If Nezarec isn't blocked while attacking, put a
stun counter on each tapped creature you don't control.
If a creature with a stun counter dies, its
controller takes damage equal to its toughness.
If Nezarec is in your graveyard or command
zone, creatures you control have Intimidate
