Charging Hellrazers

As an additional cost to cast Charging Hellrazers, sacrifice one or more creatures.
Create an 8/1 Demon Elemental creature token with a +1/+1 counter on it for each creature sacrificed. If a sacrificed creature had Trample, this creature token gains Trample permanently. The same is true for First Strike, Double Strike, Flying, Haste, Vigilance, Deathtouch, Menace, Indestructible, Lifelink and Hexproof.
