Stregoneria
Distruggi una creatura bersaglio. Crea due pedine artefatto Tesoro incolori con "
, Sacrifica questo artefatto: Aggiungi un mana di un qualsiasi colore alla tua riserva di mana".
If the target creature is an illegal target by the time Contract Killing resolves, the entire spell doesn’t resolve. You won’t get Treasures. If, on the other hand, the target is a legal target but isn’t destroyed (most likely because it has indestructible), you’ll get Treasures.
