In this meta you almost certainly want 4 Hurkyl's Recall in the sideboard to fight affinity, kci, and Tron.

You have considered Cryptic Serpent? It's pretty easy to cast in this deck and is another giant butt. In particular, it doesn't die to fatal push, which otherwise looks like a problem card.

I've been toying with idea of snap-serpent-thing in modern. I think it has potential.

Expensive spells like Insidious Will and Exhaustion are out of place in a deck with a 17-land manabase (and the former pales in comparison to good old Cryptic Command). Flood of Recollection is also a bit on the durdly side for my taste. If you want big spells, I'd consider running a few more lands, and considering Tempest Djinn as a backup threat.

I think you need a few more creatures - about 11 or 12 total. The reason is, that you really want one on your opening hand, and you can't really be sure of that until you have 11 or 12 creatures. If you don't have a creature, you have to hold out, while waiting for one, and could easily have spent a lot of you cheaper cards waiting 3 or 4 turns... and then neither delver, nor TitI are any good.

My suggestions: Add 2 Nimble Obstructionist, and 2 Judge's Familiar. A Faerie Conclave wouldn't be bad either. To make room for them, you could drop the 2 Insidious Will (I know, they have a secondary function in being pitched to Disrupting Shoal, but still 4 mana is awfully much for a 17 land manabase, also when counting in cantrips), a Remand and a Flood of Recollection. I'm not so impressed with Remand in modern - spending 2 mana on sending a 1 cmc discard or removal spell back to hand just doesn't feel like a winning move, not even with the cantripping. And Flood of Recollection just isn't good. You spend 2 mana in your turn, to get a card back in hand. My guess is that you'll rarely have more than 4 lands in play, so playing it and keeping up mana for more than one counterspell is going to be a challenge. Most cards in modern cost 2 mana or less, so most opponents can drop one semi-important spell after your flood of recollection, and threaten to have one more... if you counter the first one, you're out of mana, and they play the next spell. If you let the first spell go, no more spells will follow. You could exchange one of them for an Isochron Scepter, I guess.

Have you considered Spreading Seas for mainboard? It does give a pretty solid tempo-advantage against a lot of possible opponents, and some are really wrecked by it (getting 1 or 2 extra turns against tron can be really important).

Curse of the Swine can be a pretty surprising card out of the sideboard. goodbye goyf, hello piglet. Single copy only.

Squelch is solid in monoblue sideboards. It takes all kinds of nastyness and makes it go away. Planeswalker activations, Oblivion Stone, fetchlands... it doesn't matter, and it even cantrips.

Flood of Recollection really should be Snapcaster Mage or nothing at all.

I strongly recommend more land in the form of Faerie Conclave and Ghost Quarter/Field of Ruin.

More cantrips are really needed to support such a low mana base.

Think Twice would be a good replacement for Flood of Recollection

At the moment you are going to have a fair sized gy by turn 4-5, why not use it. The two best options to do so are 1-2 copy's of Logic Knot and 3 copy's of Cryptic Serpent

I would probably put spreading seas in SB as they are not going to be highly relevant most of the time.

With the amount of combo in modern Psionic Blast may also be worth a mb slot, as all your other removal is bounce based, (as the deck lack enough threats to close the game quickly)

The deck feels like it also what's some hard counters rather than just spell bounce, have you considered a play set of Rune Snag ?

Seems solid! Def gonna play!
