Stregoneria
Metti un segnalino +1/+1 su una creatura bersaglio che controlli. Un'altra creatura bersaglio la blocca in questo turno, se può farlo.
If you attack with the first targeted creature but the second targeted creature isn’t able to block it (for example, because the first targeted creature has flying and the second one doesn’t), the requirement to block does nothing. The second targeted creature is free to block whichever creature its controller chooses, or block no creatures at all.
