Choy a'Thark, Wind of Death

Flying, Trample.
Whenever Choy a'Thark deals combat damage to
a creature if that creature would die this turn put
a poison counter on target creature you don't
control for each demon you control.
"The huge green beast was soon identified by the
horrific smell which emanated from it, that made all
gasp and choke as its wings beat the air."----- Greva, historian.
