Stregoneria
Una creatura bersaglio prende +3/+3 fino alla fine del turno e deve essere bloccata in questo turno, se possibile.
If each creature the defending player controls can't block for any reason (such as being tapped), then the affected creature isn't blocked. If there's a cost associated with blocking the affected creature, the defending player isn't forced to pay that cost, so it doesn't have to be blocked in that case either.
