Stregoneria
Questa magia ha lampo fintanto che ci sono cinque o più valori di mana tra le carte nel tuo cimitero.
Rimetti sul campo di battaglia una carta creatura bersaglio dal tuo cimitero.
The game checks whether it is legal to cast a spell before costs are determined or mana abilities are activated while casting it. If cards are removed from your graveyard after that point, such as by exiling Jack-o'-Lantern from your graveyard to pay for its mana ability, this won't affect whether you can legally cast Graveyard Shift, even if that reduces the number of mana values in your graveyard to below five.
