Touch of the Void

The exile rider is what justifies charging a mana over red's usual three-damage rate. Ordinary burn drops a creature into the graveyard, where recursion, death triggers, persist and undying counters, and reanimation plans can all still mine the corpse; this one strips the body from the game entirely when the damage proves lethal, closing the loops that make a kill feel provisional. Devoid does the second job: the spell resolves as a colorless source on the stack rather than a red one, which matters to the cards that read the distinction (its color identity stays red, owing to the in the cost, but on the stack it registers as colorless). The trade-off is blunt. Pointed at a face or a planeswalker, the exile clause does nothing, so you are paying extra for a rider that is blank against a large share of its possible targets. What you get back is burn that answers graveyard-adjacent problems cleanly and slots into a colorless-matters shell without watering it down. This is not a generalist's removal spell; it is a tuned answer to creatures that want to die, leaning on devoid and the exile clause to earn a price red would otherwise never accept.
