The stack is the graveyard right?

No, the stack is the way in which spells cast resolve.

If you don't want to buy in to Celestial Colonnade, Creeping Tar Pit is another good option.

Instead of Jace, Architect of thought you should run Jace Beleren or Jace, Memory Adept and if you ran Liliana Vess with Jace, Memory Adept you could tutor for cards. Another thing you should use is Monastery Mentor that card just creates tokens fast.

@celestite4: Thanks for the suggestion about Tar Pit, I'll see about that one. @enigmaheat: Monastery Mentor isn't all that great for modern because it dies to bolt. Also, while Beleren is good and I used to run Vess, Architect is better and Vess was to expensive to drop. However, I will be looking into the possibility of Narset Transcendent. What do you guys think about her?

I feel like Narset Transcendent will be very good. It will draw you a card more than half the time. If you use her -2 to rebound Supreme Verdict, you set the opponent back considerably, while not setting yourself back much at all, especially if you have man lands like Creeping Tar Pit or Celestial Colonnade. You can also get a ton of value by rebounding Esper Charm to empty the opponent's hand and/or fill yours. Rebounding Lingering Souls should be nice too.

Narset Transcendant is amazing for any control deck though if you want to be even more efficient with her use stuff like Serum Visions, Gitaxian Probe, Ancestral Vision, and Think Twice. Give them rebound and you are drawing twice the amount of cards.

You definetly need Celestial Colonnade

I might look into getting some Colonnades, if I did how many do you think I would need?

4 colonnades always have a playset

Have you thought about Batterskull?

Yes, I actually just ordered one.

You're running W/U/B, there are better Delve options than Logic Knot. You'd be better off with a 4th copy of Remand and a Murderous Cut OR Tasigur, the Golden Fang. Tasigur is very good and you're already running the perfect deck shell for him. You could easily support 2 Tasigurs with this deck.

I'd also suggest dropping the Think Twice altogether. It's not really great draw and frankly you are already running better options like Sphinx's Revelation and Esper Charm. No need to over-do it on the draw. This is a control deck through and through, you need to pack all the control you can or you'll find yourself with a bunch of draw in the early game and nothing to cast. That'd open room for Tasigur and a 4th Lingering Souls, which you should run as that card can just win games all on its lonesome. Tasigur can also help in the late-game with card advantage.

Creeping Tar Pit is pretty great, definitely throw 2 copies in as a form of some alt damage. I might also consider dropping 1x Supreme Verdict for 1x Detention Sphere in the main board, then put 2x Supreme Verdict in the sideboard for creature heavy decks. It can be a dead draw against a lot of decks and you're already running a lot of removal.

The last thing I would say is that your planeswalkers could be better. If you're going for budget then what you're running is fine, but Liliana of the Veil is just too god to not run in this type of deck. Sooo powerful, especially if you include Delve for Tasigur. You could easily run all 4 if you can afford them. Other than that, I think you really have a grasp on Esper control, the deck looks fun! I play Mono-U Tron control, I'd love to get your opinion on my list: The Age of U|Tron

Oh, and I forgot the most obvious card exclusion here, Thoughtseize/Inquisition of Kozilek. I'm sure you're aware of them, but they are both excellent in Esper control.

Sword of Feast and Famine and Sword of Fire and Ice are two cards that would go good in this deck.

+1 nice control package.

Tasigur, the Golden Fang would be a better use of your graveyard than Logic Knot.

Followed link from the other Esper deck. This looks more like mine as well. Except the Jace and Sphinx. Nice work plus 1

Where is Shadow of Doubt?

Is there a reason you aren't running Snapcaster Mage?

Expense

Is he back up crazy high again? I was psyched when MM2 came out and I gaffled Vendilions and Cryptics right up

When MM2 came out he shot up even higher.

I haven't checked. I have 2 luckily obtained them cheap and no need to get more.

Woo, esper! Have you considered Tasigur, the Golden Fang? He preformes very well as a finisher, and landless card draw in the late game.
