You don't seem to have any way to remove things after they've hit. Perhaps a mass bounce spell like Cyclonic Rift?

You were completely right about that. I ended up dropping a Serum Visions and a Electrolyze for two Cyclonic Rift and on a related note, 3x Turn Aside came out and 3x Vapor Snag came in.

What do you ever Reverberate? Even if it's Lightning Bolt, I can't see this helping because you won't be able to Reverberate anything with any significance until turn 4 or 5. I think you should drop it and play Mana Leak over it.

I read in your post that you dropped Serum Visions due to budget reasons. You play Index but I don't think that's good enough as it gives very little advantage (card advantage is stronger when you actually draw the card) so in it's place I suggest Sleight of Hand.

Usually the Reverberate are for when I don't have a counterspell and my opponent is trying to bounce one of my permanents or counter one of my spells.

Is Sleight of Hand even legal in Modern? I've never tried to play it before... so I guess I wouldn't know.

I guess it is Modern legal. Didn't even know it was reprinted in Ninth Edition. Cool, I'll make the swap.

I'd take out Atarka's Command for cryptic command. If that's out of budget range I'd put in a Logic Knot and two Gitaxian Probes.

Chubbub excellent idea. it is done.
