This seems like the start of a decent list, but I don't think talrand is doing anything for you. I would cut him and vendilion clique (which is, imo, overrated), and rock full playsets of snapcaster mage, and true-name nemesis. I think you probably want 23 lands, though 22 might be doable. You should run either mishra's factory (maybe 2 of), mutavault, faerie conclave and wasteland (3-4), and add riptide laboratory (1-2) so you can bounce your snapcasters for extra shenanigans (should work well with curfew). Jitte and shackles probably aren't doing much. You have no way of tutoring jitte, and your list is very creature light, so I don't see the point, and shackles hasn't been good since abrupt decay was printed. Cut them, maybe the two ponders as well (you have enough card selection), and maybe add a set of
boomerang to help you slow your opponent down in the early game. For that matter, you might even be able to shave a top, though that's entirely up to you.
Since they can only play one land per turn, you should be able to slow them down pretty heavily between boomerang, back to basics, and wasteland, and boomerang will also let you bounce their planeswalkers and threats, giving you time to develop your own board. Doing this might even open up the chance to run daze, though I'm not sure that's such a great idea in this type of shell. Spell snare is great, and you might want 1 or 2 more counterspell, though I'm not entirely sure what you'd cut. Maybe spell pierce? I think it's better in tempo builds, and tends to shine more against removal than anything else; you aren't particularly worried about removal, and should be more focused on keeping your opponent's board empty. Counterspell and spell snare are probably better in outright control builds.
I think if you made these changes, the list would be quite strong. With a couple of manlands and TNN you'd have good inevitability, along with snapcaster for a bit of additional back up. Just make sure you keep deathrite shaman off the field, and try set up your lock early.
Cheers!
EDIT: maybe back to basics with utility lands isn't such a great idea... maybe replace it with something else? Crucible might be an idea, since you can then wasteland lock them, and have fetches on demand to shuffle away the top of your library. Also, add a few more fetches, since you're running brainstorm, jace, and top. I would run at least 8 fetches minimum with this mana base, maybe 10.
