Ornstein and Smough

Trample, Menace, Lifelink
When Ornstein and Smough dies, create a
legendary 4/4 dragonslayer token named Ornstein
and a legendary 4/4 executioner token named
Smough.
When either tokens die, you may sacrifice the
other. If you do you may return Ornstein and
Smough from the graveyard to the battefield.
