Vigilant Knight Paladin

If you have 4 or more Maintenance counters, you
may pay {r}{r} instead of its normal mana cost.
{1}{r}, {t}: Vigilant Knight Paladin gets -1/-0 until
end turn, then deal damage equal to Vigilant
Knight Paladin's power to another creature. If
that creature dies, untap Vigilant Knight Paladin.
He must serve the Emperor, and defend the Imperium.
Thus should a Knight rule himself.
