Spectre of the Shadowblade

As long as Spectre of the Shadowblade is tapped,
it has shroud.
Whenever Spectre becomes blocked, you may
remove it from combat. If you do, it deals
damage equal to its power to target creature
defending player controls. If a creature dies as a
result of this damage, put a +1/+1 counter on
Spectre.
{b}{r}, {t}: Destroy target creature. Its controller discards a card.
You've seen my work. It speaks for itself.
