Volcanic Salvo

The printed cost of twelve mana is a fiction the card never expects you to pay: the discount clause reads total power off the board, and any wide or fat red creature deck turns that number into something absurd. A single 6/6 knocks it to a six-mana wrath-for-two; a couple of hasty threats can float it down toward its floor. That is the whole trick, and it is an old one dressed in new math. This is the removal-side descendant of cost-reduction payoffs like Draco or the affinity-era artifacts, where the mana value on the card is a ceiling you build to dodge rather than a price you meet. The design synergy is that the reduction and the effect pull in the same direction: you want a full board to cheapen it, and a full board is exactly the position where clearing six damage from two creatures or planeswalkers matters most to you as you set up the alpha strike. It rewards the deck that is already ahead on power, which is a deliberate choice: the deck behind on board cannot afford twelve mana and gets nothing, while the deck ahead gets a cheap, flexible two-for-one that clears blockers or answers a planeswalker before the alpha strike. A build-around by construction, it does nothing for a control shell and everything for a creature deck asking how to punch through the one turn a stalled board needs to break.
