Tadnora, Judges of Obzedat

Deathtouch, Lifelink
When Tadnora enters the battlefield, each player sacrifices a creature and gains life equal to its combined power and toughness.
Whenever a creature dies, you may pay {w}{b}, if you do exile it. If a creature is exiled this way,
you may pay life equal to its power and put it onto the battlefield under your
control instead.
