Boros Energy is a removal-and-sweeper deck (Galvanic Discharge, Path to Exile, Wrath of the Skies, Wrath of God) rather than an artifact deck, so Vandalblast comes in mainly as a blowout on their Cori Mountain Monastery or animated lands, and as insurance if they bring in Wear // Tear against your Urza's Saga. Soul-Guide Lantern answers Solitude and slows their Avengers Disassembled graveyard plan while cycling away when dead. Play around Wrath of the Skies and Wrath of God by not dumping your whole hand at once, and use Cori-Steel Cutter and Emry to rebuild through a sweeper. Keep Metallic Rebuke and Unholy Heat as your primary interaction against their removal suite.
