Varinkir, the Progenitor

{1}{b}{r}{w},{t}: Any number of target players
may sacrifice a creature. If an opponent does, they
draw X cards and lose X life where X is the sacrificed creature's power. You can't attack them
or planeswalkers they control with creatures this
turn.
Whenever a player sacrifices a creature, if it's the
first creature they've sacrificed this turn, create
X 1/1 black and red Vampire creature tokens with haste, where X is the sacrificed creature's power.
