Obliterating Bolt

Four damage for two mana is already a premium rate against creatures, but the exile rider is what shifts this from a damage spell into an answer aimed at a specific problem: recursive threats. Deathtouch blockers that come back, undying and persist creatures banking on a death trigger, planeswalkers that would rather be reanimated than gone. Most burn gives you the damage and lets the graveyard sort out the rest; this one closes the loop by making the death permanent, provided the target dies this turn. The conditional is precise. Exile only applies if the target would actually die this turn, so it does nothing against a creature that survives the turn, and nothing against one saved by regeneration or a shield counter. Being a sorcery is what fixes it to your own turn: this is proactive removal by card type, priced to fit an aggressive curve, rather than a reactive catch-all held up to answer whatever crosses the stack. The wider point is a small but deliberate strain in red's design toward answers that address graveyard value directly, giving mono-red something it historically lacked: a way to permanently deal with a creature that expects to come back for a second act, without splashing white or black exile effects to do it.
