Card intelligence brief
Destroy target artifact you don't control.
Overload {4}{R} (You may cast this spell for its overload cost. If you do, change "target" in its text to "each.")

Sales, inventory, and broader Magic demand signals for Vandalblast.
RSG intelligence changes as sales, inventory, and market signals change. A demand signal is not a binding purchase offer.
Start with the closest functional alternatives, then narrow by what matters for your deck.
