Tanar'ri Dretch

Tanar'ri Dretch cannot attack or block alone.
Whenever you cast a Demon creature with higher
power than Tanar'ri Dretch, create a token that is
a copy of Tanar'ri Dretch.
Veteran paladins are keenly aware that the
unintelligent and lowly Dretch can be as deadly as any
other demon when enough incur into the material
plane. They are not taken lightly.
