3 Sphinx's Revelation? Most decks that use the card ever run more than 2 and they're usually running at least 25 lands. I can't imagine you'll ever get too much out of it on 21 and if you do it'd be super late into the game.

bigguy99 I'm unsure about that, to be honest. It has usually been a dead draw. I might drop them to get another sword and 2 more lands.

That's actually exactly what I was getting at - I was a bit shocked, frankly, to see three of the card in the deck. I think what you've done to balance the numbers is fine (I really like adding two more lands) - but Sword of Body and Mind is just bad in Modern. I'd go up to three Remands, down to three Mana Leaks, and add another KotR and Myth Realized. I think that adds up to 60 (after taking the sword out).

I would suggest not running Myth realized, this deck can't capitalize on it and it isn't even that great of a card - especially not with swords because he won't stay equipped. I think 1 Sphinx's Revelation is fine and will work well with the amount of ramp you run. For the other two slots try running 2 Qasali Pridemage for the extra reach and exalted bonus.

I would also suggest dropping Sword of Light and Shadow, unless your creatures die it isn't useful. Instead I highly highly recommend that you run 1 Batterskull mainboard. You can play it turn 3 off a cobra and a fetch land.
