Toph, the First Metalbender

Nontoken artifacts you control are lands in addition to their other types. (They don't gain the ability to for mana.) At the beginning of your end step, earthbend 2. (Target land you control becomes a 0/0 creature with haste that's still a land. Put two +1/+1 counters on it. When it dies or is exiled, return it to the battlefield tapped.)
