Disaster Radius

The reveal cost is the whole transaction here: you pay seven mana and show a creature you are not playing, and the spell hands you a board wipe scaled to that creature's mana value. The design quietly rewards the kind of fatty deck this color rarely gets to build around, since the biggest thing in your hand sets the damage ceiling. Reveal a seven-drop and you scorch the opposing board for seven, then cast that same seven-drop next turn; nothing about the cost actually spends the card you show. That is the wrinkle that separates it from a flat-X sweeper like Bonfire of the Damned or Earthquake: the size is decoupled from what you tap out, smuggled in through information you reveal rather than mana you commit. The catch is that it touches only your opponents' creatures, so it is one-directional removal that keeps your own board intact, and at sorcery speed it asks you to wipe on your turn and then close. It also can't be cast at all if your hand is creatureless at the moment of casting, which ties a red sweeper to a creature-forward build rather than a spell-heavy one. A heavy, top-end design built for a deck that wants both the wrath and the threat in the same colors.
