Nature's Ordeal

Shroud, Indestructible, Fading 5 Whenever you tap a land for mana, that land doesn't untap during your next untap step.
When Nature's Ordeal is put into a graveyard from the battlefield, if it had no time counters on it, you get an emblem with "Creatures you control get +1/+1." and "Whenever you tap a land for mana, add two mana of any color to your mana pool."
