Zargothrax

Hexproof from instants, sorceries, and
unequipped creatures.
Sorcery spells you cast cost X less to cast, where
X is Zargothrax's power, and may be cast as
though they had flash.
Whenever you cast a sorcery spell, put a +1/+1 counter on Zargothrax and each zombie and
demon you control.
"I am the Bane of Cowdenbeath,
the Scourge of Auchtermuchty,
Arch-foe of the Questlords of Inverness."
