once you're done showing off, this is the version of the deck you'll probably actually want to play with your friends.
it's still very good and fun! the lack of Gamble and Wheel of Fortune make it quite a bit slower; Seething Song has been banned since 2013 on account of when Storm decks took the Modern meta by, well, storm, and could become unbanned any day now, since it's not really that powerful.
Reforge the Soul and Bedlam Reveller are pretty obvious as substitutions. they're worse wheels, though one will give you a solid creature and the other occasionally is actually a slightly better wheel, if you're lucky enough to draw into it with nothing to lose in your hand.
Mana Geyser, on the other hand, can feel like dead weight unless it's the midgame and you're playing multiplayer. in general, this deck is better in a multiplayer setting!
the combo in the modern-legal version is slightly less speedy. but once it lands, it lands in just the same way: with a big old explosion of game ending damage. it's not as good, but it can be--I've tested it and combo'd out on turn 4--and meanwhile, your friends should hate you slightly less for running it!
