Martok's Eternal Disdain

Destroy any number of non-token artifacts and enchantments with a total combined converted mana cost less than or equal to the number of Forests you control. For each permanent destroyed in this way, create a 1/1 Green Elemental creature token.
When the goblin shaman-king Martok was slain by Arlonni, with his last breath he cast his soul into the astral winds. His avatar returns again and again, tearing down the great works of Azkanath.
