Lifeborn of the Forest

{p/g}{p/g}{p/g}{p/g}{p/g}{p/b}{p/b}: Manacharge (Add {g} to your mana pool for each of your opponents)
When Lifeborn of the Forest Manacharges, its activated ability costs {p/g} less to cast.
This particular manaborn was born of a Manacharger tainted by phyrexian oil. This creates a most unusual effect.
