Sonic Seizure

Three damage for one red mana is the rate every burn spell wants, and this one buys the discount in cards instead of mana. Random discard is the tax: you pay the full Lightning Bolt effect for a single red, but in exchange the spell strips a card from your hand without letting you pick which one. That asymmetry is the whole proposition. The cost is not life or extra mana but information and option-density, the two resources a low-curve red deck values least when it is winning the race and most when it is flooding out. The randomness is what keeps the deal from being free: a discard-of-your-choice would have been strict upside in any deck happy to ditch a late land, but randomizing the loss means your one relevant spell can go to the bin as easily as your dead card, and the variance scales against you the longer the game runs. It sits among a small graveyard-era family of spells that paid their discounts in cards rather than mana, designed for a set where discarding was meant to be construction rather than pure loss. Strip away a deck built to make the bin an asset and it reads as a coin-flip Bolt: same damage, same target line, but a string attached that pulls hardest exactly when you can least afford it.
