Feitiço
Destrua todos os artefatos. Depois, Assalto Estrutural causa a cada criatura dano igual ao número de artefatos colocados em cemitérios vindos do campo de batalha neste 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.
