Shatterstorm

Every artifact on the battlefield is gone, and the controller does not get to keep one: that sentence is what this card established, and what every softer successor has had to define itself against. The "can't be regenerated" line is what gives the spell its absolutism; it strips the artifact player of the one out a mass destruction spell normally leaves open (regeneration shields), and converts the card from a threat into a verdict. The double-red commitment is the cost discipline that keeps an effect this total honest, a counterweight against a sweeper the opponent cannot meaningfully play around. Wizards has been printing gentler versions for decades, each trading finality for flexibility, splash-ability, or selectivity: Vandalblast scales by mana cost, Meltdown scales by X, By Force gives you a count, Shattering Spree splits copies onto the stack. None of them say the same thing. That unconditional clearing is what an answer to an artifact deck is supposed to mean, and the meaning was fixed here before anyone tried to soften it.
