Vigilance, Deathtouch
Whenever a Groomsman enters the battlefield
under your control, creatures your opponents
control get -1/-1 until end of turn.
{t}: Add {g} for every Groomsman creature you
control. Instead, add mana of any color to cast
another Groomsman card from a graveyard.
Wedding Party (At the beginning of your turn, if
you control all other Legendary Groomsman,
you win the game.)
