Dysz, Heir of Damia

Deathtouch
Gorgon creatures you control have poisonous 1.
Whenever a Gorgon you control becomes blocked,
put a petrification counter on each creature that
were declared as a blocker for that creature.
A creature with a petrification counter becomes
a colorless artifact creature with defender and with
base power and toughness 0/X, where X is its
toughness, in addition to its other types.
