Sorin, Bloodsworn Nemesis

Flying, Haste
When Sorin, Bloodsworn Nemesis enters the battlefield, count the number of vampires you control, then draw that many cards, rounded up.
Then you lose that much life.
{b/r}{r/w}{w/b}: Vampires you control get +2/+1 until
end of turn.
The rightful heir to Markov Manor.
