2 rulings from Wizards of the Coast
- 29 April 2022Structural 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.
- 29 April 2022If 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.
