Chea, Friend to Many

Familiar spells you cast have flash.
(Bats, Birds, Cats, Dragons, Faeries,
Foxes, Frogs, Imps, Lizards, and
Spiders are familiars, as well as any
creature with "Familiar" in its name.)

Tap: Add X{g} and each opponent
loses X life, where X is the number
of familiars you control.
