This hits so many staples.
Standard it's probably just going to be like Jace and Swiftspear, but in Modern, hoo boy.
Past in Flames, Snapcaster, Summer Bloom, Spellskite, Pestermite, Exarch, Bob, Maelstrom Pulse, Azusa, Scapeshift.
I don't play Legacy or keep up with it, but I'm sure this card is relevant against a lot of cards in that format as well.
Bolt is much more flexible though. Sure, you might use it for removal more often than doming, but imo, replacing a card as good as Lightning Bolt for a card that specifically targets one creature weakens all your other matchups instead. Bolt can also relieve pressure on your storm count: dome your opponent for 3 (6 if Ascension is active or if you already cast PiF, even 12 if both) and makes it much easier to get a killing Grapeshot.
Volley is very good as an answer card for Rhetoric (and probably other cards I'm forgetting), but Bolt is simply too good to cut out 4 in your sideboard.
