Shameful Death

Shameful death cannot target creatures that
are: artifacts, black &/or vehicles.
The top creature card of your opponent's
graveyard comes into play tapped under
your control. This creature loses all it's
printed colors and is now a black creature.
"The secret is to taint your opponent,
turn them to evil just before they die.
Then, if you wish, bring them back
at your side... this is dark wisdom."
