Ashenscale Razeslither

Deathtouch, Firststrike, Trample
Ashenscale Razeslither enters the battlefield with
X +1/+1 counters on it, where X is the total life
lost by your opponents this turn.
It is the whim of evil forces made real, slithering across
the world, destroying the living and desecrating the
dead. Its hiss brings madness, and its fangs drips with
venom that no amount of magic healing can cure.
