* 702.82. Unearth
*
* 702.82a Unearth is an activated ability that functions while the card with
* unearth is in a graveyard. "Unearth [cost]" means "[Cost]: Return this card
* from your graveyard to the battlefield. It gains haste. Exile it at the
* beginning of the next end step. If it would leave the battlefield, exile it
* instead of putting it anywhere else. Activate this ability only any time you
* could cast a sorcery."
