Istantaneo
Una creatura bersaglio che controlli e fino a un'altra creatura leggendaria bersaglio che controlli infliggono ciascuna danno pari alla propria forza a una creatura bersaglio che non controlli.
If one of the two target creatures you control is an illegal target as Friendly Rivalry resolves, the other will still deal damage equal to its power.
If the last target is an illegal target as Friendly Rivalry resolves, or if both of the first targets are illegal targets, no creature deals or is dealt damage.
