Ugyldig, All-Consuming

Hexproof, Indestructible
Whenever a creature dealt damage by a zombie
you control dies, return it to the battlefield
under your control. That creature becomes a
zombie in addition to its other types.
{w}{u}{b}{r}{g}: Exile another target zombie until
Ugyldig, All-Consuming leaves the battlefield.
Put a number of +1/+1 counters onto it
equal to the exiled creature's toughness.
