Death Knight

Menace
The first time this creature would be destroyed
by combat damage or an effect, instead prevent
that damage and Death Knight gains indestructible until the next phase.
When a creature is destroyed by Death Knight in combat you may pay {1}{b}. If you do, exile that
card and create a token that's a copy of that card
with power and toughness 1/1. The copy is a
black zombie in addition to its other types and
colors.
