Unhallowed Rustblade

Armor 4 (This creature enters the battlefield with 4
armor counters on it. If it would be dealt damage, you
may remove any number of armor counters on it to
prevent that much damage.)
Black Metal (Whenever this creature deals damage,
target player receives reduced healing equal to the
creature's power.)
His blade thirsts for blood. His armor hungers for battle.
He serves both needs.
