Ravok-village Cultivator

Whenever a land you control is tapped for
mana if no other creature you control shares a creature type with this you may tap Ravok-villlage Cultivator to add two mana of any
one color to your mana pool instead of the
mana added by that land.
"So frantic and wild, are you sure they speak for
the trees?" Lorek, the Druid
