Stregoneria
Distruggi tutti gli artefatti, poi l'Assalto Strutturale infligge a ogni creatura danno pari al numero di artefatti che sono stati messi nei cimiteri dal campo di battaglia in questo turno.
Structural Assault counts the number of artifacts that were put into graveyards from the battlefield this turn for any reason, not just because they were destroyed by Structural Assault.
If a player controls an artifact creature with a shield counter on it as Structural Assault destroys all artifacts, a shield counter will be removed before Structural Assault deals damage to each creature. Unless that artifact creature has another shield counter on it, the damage won't be prevented.
