Barrax, Rotting Tyrant

Deathtouch
When Barrax, Rotting Tyrant enters the
battlefield, exile another creature until Barrax,
Rotting Tyrant leaves the battlefield.
Then create a Legendary 5/5 black zombie
dinosaur creature token with Deathtouch named
'Barrax, Tyrant of Rot', and "Whenever this
creature leaves the battlefield, return Barrax,
Rotting Tyrant from your graveyard to your hand."
