Lightning Boltremoval$2.13The premier 1-mana red burn spell, trading one less damage for a cheaper cost and more efficiency. It fills the same role of flexible instant-speed removal or reach to the face.
Shockremoval$0.30A very similar instant-speed burn spell that also hits any target, though for less damage. It is a common budget substitute for cheap red removal and reach.
Play with Fireremoval$0.22Another cheap instant burn spell that can hit any target and doubles as a bit of utility with scry. It is close in function while offering slightly less raw damage.
Abraderemoval$0.32Shares the same 2-mana instant-speed removal slot and can answer small creatures, with bonus artifact removal. It is broader but less direct than Searing Spear.
Incinerateremoval$0.30A classic 2-mana instant that deals 3 damage to any target, just like Searing Spear. It is one of the closest functional matches.
Boros Charmremoval$5.00While not a burn spell, one mode deals 4 damage to target player, giving similar direct-damage reach in red-based decks. It is more flexible but not removal for creatures.
Skewer the Criticsremoval$0.21A cheap red damage spell that often costs only one red mana and can go to any target. It serves a similar role as efficient reach, especially in aggressive decks.
Lava Coilremoval$0.07Same general mana range for red removal, trading flexible targeting for stronger creature exiling. It is better against creatures but worse as direct damage to players or planeswalkers.
