It's banned in modern and he looks a lot like a modern deck with Path to Exiles, Nacatls, Kird Apes, etc.

You look pretty modern oriented. Are you aware it's not legal because of the Bloodbraid Elf? Or just don't care?

I'm completely fine with Molting Snakeskin to solve the Sidisi problem. Just bug the piss out of Relemin until he looks at it and gives some feedback. In the meantime, you may want to proxy this deck and see how it plays out. When playtesting a deck, remember to pay attention to it's strengths and weaknesses and imagine if some other cards would come in a lot more of use than others you may have in there. Another card you could possibly consider is Embodiment of Spring. Defender, mana ramp, and delve/Sidisi fuel all in a 1 drop common.

http://www.mtgvault.com/spiffmeister/decks/s-sultai-gravejuice-2/ heres a link to another guys Sultai that looked promising, though it used a bit more delve than yours does.

I say! Jolly good library here young chap!

Okay sorry, thought me and Jacob would discuss this, didn't know it was yours. I'm going to go over the cards individually and give my thoughts.

Clever Impersonator - Unless you are using it on opponent's permanents I don't see a reason for it. Especially as a 1 of. The creatures of yours you could be copying are just the early games stuff to set up for later such as Caryatid, Courser, Weaver. You won't need to copy this to aid you into getting to late game, rather as a late game card in itself and it doesn't work with your bombs. Sidisi is legendary, Garruk is a planeswalker, Prognostic Sphinx probably won't be your main finisher, and you can't copy Empty the Pits.

Prognostic Sphinx - I am actually a fan of this in the deck. It's a 3/5 that has pseudovigilance that also aids you in delving. Being a 3/5 it can easily attack then block and protect from things such as Sarkhan, Stormbreath Dragon, and pretty much anything else that shows up. On top of that the scry is great, but sadly can't force things into the graveyard.

Rakshasa Deathdealer - Great 2 drop that your always happy to have, even later into the game if you draw it, it is not just a dead card like most 2 drop creatures would be. If this card doesn't work out, sub in Satyr Wayfinder. I think your the guy that told me you don't like him but he's perfect in decks like this.

Sidisi - Fun little card to tinker with, unfortunately he can't protect himself meaning he is easily susceptible to death if you try and trigger his ability through offense. Although if you can bide your time with him and use other things such as Nyx Weaver, then he could easily become a threat without needing to do anything. Kind of a hit and miss card it seems, but if it works for you go ahead and do it.

Sylvan Caryatid - Must have 4 of. Too good of a defender and mana ramp to not have.

Courser of Kruphix - Also a must have 4 of, it helps trim through your deck quicker and allows you to gain some life in the process. Again, another good defender.

Nyx Weaver - Perfect fueler for Sidisi and Emptying your Pits on your opponent. I'd run 3-4 of for utility purposes and I just love it.

Dissolve - Seems a bit meh early game because you need to play other things and tap out or near tap out to do so. Could easily save your life later in the game I suppose. Needs some play testing.

Empty the Pits - Only needed as a 1-2 of because your want to spend so much delve into it to end the game. It completely turns the tides if you can hit it for 5 or 6 zombies.

Murderous Cut - Unfortunately, black removal is a bit lowered in this set so I know you don't have a lot to work with but this would probably be your best bet. 3 of is fine by me. If all else fails you can always hardcast it, unlike some other delve cards it isn't too expensive. If it ends up not working as well as you hope, replace it with Hero's Downfall to deal with pesky planeswalkers running around, and maybe be more mana efficient.

Sultai Charm - A great card because it is so versatile. See how useful it truly is in the meta first though.

Garruk - Seems like a "Win more" card imo. By this I mean he doesn't really get you to win the game, but to just do it because you've pretty much already won. I wouldn't even actually run him, but replace him with a cheaper bomb.

Thoughtseize - Everybody loves hand disruption. Great card.

Lands - If this mana base works for you then go for it. I'm sure you already know, but fetchlands are a necessity if your willing to pay for them.

Overall impression - I enjoy the deck. I only have 1 complaint on it. You aren't running much of anything to put things into the grave quickly, but then again I suppose you aren't running much delve to begin with so it should work out fine as long as things are dying.

Also, do you own all these cards or just having fun on the vault?

Cut an Empty the Pits for your fourth Sylvan Caryatid. It's a must have playset in these kinds of decks.

The 4 mana 6/6 flying trample is enough of a bonus imo :P

Assuming you can consistently drop it.

Also, sideboard in Blightning for those pesky control decks, it adds so much pressure to them. Duress may also be a good choice against them.

You would probably benefit from adding in more Nykthos for consistency. And more land in general.

I may make a spinoff of this deck, it looks interesting to play.

Please, drop it to about 60 cards. Much better that way.

Interesting interaction between Launch the Fleet and Battlefield Thamauturge

Please, drop it to 60 cards lol. It's much more consistent and focused that way. You will get what you need faster.

What, no Phyrexian Obliterators? Forshame.

I don't know about the Caress. I haven't play tested with either one but in theory The Rack seems like a better option to me. I understand Funeral Charm is an Instant and will help Liliana's Caress. As for removal I mean kill spells to destroy any creatures they do manage to get. For instance, if they drop a Tarmogoyf, it will be hard for you to deal with it unless you just block it with deathtouch I guess lol.

Understandable, a lot of decks use Delver, but there is a reason for it. He's just really good. Especially when you can beat them down with a Runechanter's Pike in the air.

The self mill idea was fantastic. Grats whoever thought of that. With that being said, I feel Thoughtscour would be ideal here. One drop instant that can get you a card and hopefully buff your creatures. If you can find the room, Delver of Secrets is always a great card in these decks. It's only worth a dollar too if that's not too much.

Drop Liliana's Caress for The Rack MB. Liliana's Caress only works when they discard. At some point (hopefully quickly) they will be out of cards in hand to discard and lose life to as they will be playing them as a desperate attempt to keep up. The Rack will deal constant damage and reward you for emptying their hands. On top of making that change I'd drop Funeral Charm for a Despise or Duress or something.
I would also try to throw in some removal cards.
It would also be beneficial to drop it to 60 cards.

I'm surprised there is only one Corpsejack in here. With the reliance of +1/+1 counters it's perfect. Another interesting interaction you may not be aware of it if you have Corpsejack out, using a spell such as Bioshift will cause a double amount of counters being shifted.

Boon Satyr
Bow of Nylea
Fanatic of Mogis would be a decent 3 drop.
Chandra Pyromaster
Stoke the Flames would be perfect here, but it's probably the most expensive uncommon in standard.
Crater's Claws
Dictate of the Twin Gods
Elvish Mystic is pretty much THE 1 drop mana accelerant.
Ember Swallower could be interesting if you can function without the lands and they can't.
Fated Conflagration is a good burn card here, especially if you can get it off with the Satyr.
Fated Intervention is also good. Neither of these are expensive either.
Fellhide Spiritbinder possibly.
Flame-Wreathed Phoenix could be really good.
Forgestoker Dragon as a bomb.
Garruk's Packleader if you've got the power.
Generator Servant
Genesis Hydra
Heroe's Bane I really like for 40 cents.
Hooded Hydra. Though I've never played with it.
Hunt the Weak as psuedoremoval.
Hydra broodmaster ( you should probably get a good finisher her too, any hydra will do.)
Karametra's Acolyte... maybe
Leafcrown Dryad if your needing 2 drops.
Life's Legacy can easily put you in the lead with card advantage, Great card if your willing to sac to it.
Magma Jet because scry is awesome.
Miscutter Hydra against pesky blue decks
Nessian Asp if you have it lying around, otherwise I would just get something better.
Nessian Wilds Ravager :D
Nissa's Expedition if you have enough for low drops for convoke.
Nissa Worldwaker. Amazing but I'm not paying for it.
Nylea if you can animate her, otherwise nah.
Paragon of Eternal Wilds if you can get your hands on planeswalker Xenagos and spawn the tokens, it's pretty good.
Pheres-Band Raider also works with Paragon
Polukranos... I don't get why he's so costly. I don't even like him, but you may want to playtest. Could see something I didn't.
Purphoros could fit the theme here perfectly.
Snake of the Golden Grove if the life gain is relevant to you.
Soul of Shandalar
Soul of Zendikar
Stormbreath Dragon. 20 dollars.
Tormenting Voice maybe?
Voyaging Satyr for more ramp
Wall of Mulch to stall and draw

These are all the cards that would be relevant to your deck. Left notes aside some of them. If you have any questions feel free to ask.

It depends on if budget matters to you or not. This deck could probably use some Sylvan Caryatid, but I can't justify the cost on cards like that.

A nice SB card would be Destructive Revelry, as it helps against quite a bit in Theros and adds to your burn theme.

Polis Crusher is also another favorite of mine at 38 cents, it kind of fits in with control aspect depending on who your playing against. (Good to replace the Scrapyard Mongrel :D)

Either Xengos god or Planeswalker could fit in here, though they could a bit more expensive. The god is actually affordable if you can get the deck to work well with him, planeswalker on the other hand is probably better but 3x the cost.

Anger of the Gods may help, though I don't know the current meta so I don't know how relevant it would be.

Arbor Collosus is also really good against certain people, but either way it's good for the mana cost and the money cost.

I could go on, but meh. Just do a card search on this site for red and green exclude other colors and search standard legal only. Be way though, I think this site still includes Return to Ravnica as standard.

Last note - If your running a burn package and keep the Satyr Firedancers, make sure your burn can target them directly. Preferably both so you have options. And try to keep it at 60 cards if you can, it's just better that way.

How successful has this deck been? I want to get into modern and not completely break the bank on it until I know I enjoy it. This deck looks interesting and I'd be willing to try it out.
