Sir Vultaz, Of Old Lineage

Exalted (Whenever a creature you control attacks
alone, that creature gets +1/+1 until end of turn.)
Whenever Sir Vultaz attacks alone or with
at least three other Vampires, it gets +1/+1 for
each other Vampire you control on the
battlefield and in your graveyard.
When Sir Vultaz dies, if another creature died
this turn, you become the monarch.
