Creature - Elemental Horror 3/6, 3BBG (6) {1}{B}{G}, {T}: Target Forest becomes a 4/4 black and green Elemental Horror creature. It's still a land. Its darkened sap penetrates natural fibers and spreads its own genes. Emulation experiments are underway. - Simic research notes

10/1/2005: The effect has no stated duration, so a land turned into a creature this way continues being a creature as long as the land is on the battlefield.
8/1/2008: A noncreature permanent that turns into a creature is subject to the "summoning sickness" rule: It can only attack, and its {T} abilities can only be activated, if its controller has continuously controlled that permanent since the beginning of his or her most recent turn.
