Ulrich Vosk

Eminence -- Whenever you cast another Vampire
spell, if Ulrich Vosk is in the command zone or
on the battlefield, create a 1/1 black Vampire
creature token.
First strike, haste
Whenever Ulrich Vosk attacks, you may tap an untapped vampire you control to tap target
non-land permanent an opponent controls. That
permanent doesn't untap during its controller's
next untap step.
