|

* 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."
