Call Forth the Tempest
Two cascade triggers off an eight-mana sorcery read like a value engine, but the payoff is doing arithmetic most cascade cards never bother with: it sums the mana value of every other spell you have cast this turn and turns that number into damage across all opposing boards. This is where the double cascade earns its keep. Free spells still carry their printed mana value, so the two nonland hits the cascades throw onto the stack resolve before the sweep and immediately fatten the count. A single flip into something expensive can add four or five to the total; two flips can push the damage past the size of most creatures in play without you spending a card. The triple-red pip and the eight-mana price both point at a ramp-into-payoff turn where the goal is to have cast as much as possible before this one lands, and the cascades are engineered to keep that meter climbing on the way in. The result is a wrath disguised as a burn spell: the floor is an expensive Pyroclasm, the ceiling scales with how much your turn has already committed, and both mechanics on the card are pulling in the same direction rather than fighting over which turn to cast it. Building around it means front-loading a turn with real spells and trusting the cascades to compound what you have already paid.
