Nivina Reaper

Flying, Haste.
Firstblood 3 (When this creature deals combat
damage to a player, if it was the first to do so this
game, put 3 +1/+1 counters on it.)

For as long as Nivina Reaper has no counters on
it, vampires you control have flying and haste.

"Nothing is permanent. Especially not
the living."
