This explosive loop turns a single spark of noncombat damage into an endless cycle of greed and devastation. Once you deal that initial damage to Smaug the Impenetrable, its triggered ability responds by creating a horde of Treasure tokens. Because March of the Machines transforms every single one of those new artifacts into an artifact creature whose power equals its mana value, their sudden arrival immediately triggers Warstorm Surge. That surge of damage is channeled right back into Smaug the Impenetrable, fueling the next wave of Treasures and letting you repeat the entire process to wipe out any target and bury your opponents in infinite resources.
