Volcanic Spray

Sweeping the ground while pinging both players in the same spell is an old red trade, but the flying clause is the line that gives this its identity: it answers everything on the dirt while leaving fliers (the caster's included) above the blast. That asymmetry is the point. Decks built around an evasive air force keep their threats safe and use the spell to scour the opposing board of the small ground creatures that would otherwise race back, all without nicking their own offense. The damage to each player is the price red pays for the effect, a reminder that this is burn pointed at a battlefield rather than a clean wrath, and that the same casting can chip at a life total while it clears. Flashback is what makes the two casts worth more than the sum of their mana: the early sweep that mops up a swarm comes back from the graveyard to catch a second wave or shave the final points off a stalled race. Red rarely gets repeatable mass damage, and the exile-on-recast clause is what stops this from becoming an engine: two doses, then the card is gone. That split (a cheap board scour now, a graveyard-fueled second printing later) packs two effects into one slot, the kind of value red gets only when it is willing to point one damage at its own life total to do it.
