Personally, I prefer Restoration Angel over Eldrazi Displacer. Flash and Flying are the main reasons, plus it's out of Bolt range, unlike Displacer. Angel also doesn't need {C} for its ability, which can help clean up your mana base a bit. In Displacer's defence, Displacer costs less, and its Blink effect is reusable and usable on an opponent's creature, returning it tapped, thus removing a blocker.

I think 2x Supreme Verdict is a good sweet spot. Not too many to make it a dead card, but just enough to be there when you absolutely need its effect, which will happen.

Dam, forgot the Ascendancy draws you cards. Now I feel stupid *facepalm*

How quickly do you empty your hand? Because if it's quite quick often enough, Lupine Prototype would be worth considering.

Why no Gaea's Revenge? {5}{G}{G} for an 8/5 with Haste that can't be countered nor targeted by nongreen spells or abilities. It's also got the deck's name.

I'd also take Overgrown Battlement to 4x. It just gives you so much mana.

That looks better. More focused.

Cool.

Stormchaser Mage is arguably better than Mercurial Geists, if only for its much lower cmc. At two mana, Stormchaser is definitely a candidate for 4x.

Jori En, Ruin Diver supplies regular draw. A little slow though, as you have to play two spells to get the draw, and you can only draw once per player's turn.

Thing in the Ice both clears the board and gives you a large beat stick.

Just reread Cipher. If you can give the creature double strike, you'll be able to use the encoded spell twice. An equipment seems like the best option for this idea, which makes Fireshrieker the best option.

Tormented Soul is an excellent one drop for this deck.

There's an easier way to get a Dredge card into the graveyard on turn one that doesn't require the opponent to play a creature: Raven's Crime. Just target yourself and discard a Stinkweed Imp, then you can Dredge 5 on your second turn.

Dakmor Salvage and / or Life from the Loam help make sure you have lands to play. You will be Dredging those precious lands, so a way to return them is always useful.

I think you should streamline which Titans you want to fetch a bit. Decimator of the Provinces seems a little iffy here. Remember, you sacrifice creatures to Eldritch Evolution, so there's very little use for the Decimator's enter the battlefield effect.

Pathrazer of Ulamog's cmc is a little high. Sibsig Muckdraggers is needed to fetch the Pathrazer with Eldritch Evolution. At least all the others can be fetched off either Delve creature, but Pathrazer can only be fetched off the Muckdraggers.

Swapping out Sibsig Muckdraggers for Gurmag Angler allows for a more streamlined search engine, but that also means swapping Pathrazer for something. I suggest Golgari Grave-Troll, but if you can't get it, Golgari Thug does well too.

You may want to splash white for Unburial Rites so you can use its flashback to pop a Titan you Dredged onto the battlefield.

To my knowledge, there's one card per colour that has a similar cmc to Spectral Procession.

White - Spectral Procession
Blue - Advice from the Fae
Black - Beseech the Queen
Red - Flame Javelin
Green - Tower Above
Artifact / Multicolour - Reaper King

Another option for Sin Prodder is cards with flashback. Or some other way to be used in / returned from the graveyard.

I feel I should also point out that Goblin Dark-Dwellers can't cast Spectral Procession, etc. As their cmc is 6.

Was looking up Snow permanents in Modern that may fit this deck. I came across two that could fit:

Mouth of Ronom - as a 1of, this could be useful for that last bit of damage required in some games.
Coldsteel Heart - this is mana acceleration. Stuffy does cost {5}.

Personally, I'm not fond of the 4 mana required to cast Mercurial Geists. If it was a clone of Wee Dragonauts, I'd like it more. So 4x is troublesome. Maybe reduce them to 3x and increase the number of Curious Homunculus to 4x, it is your mana dork and its flip side is relevant.

Any reason you're sticking with just one block? Because there's some other cards in BfZ that'd fit this deck quite nicely.

That's brilliant. I didn't think of that. I'm so going to make a Sin Prodder deck with Shivan Wumpus... Wen I get back from WMCQ. Maybe even with Goblin Dark-Dwellers, depending on the spell selection.

The Rings and Forced Adaptation trigger in your upkeep, so Paradox Haze?

Was going through my cards looking for something when I found this:

Shivan Wumpus
{3}{R}
Creature - Beast
Trample
When Shivan Wumpus enters the battlefield, any player may sacrifice a land. If a player does, put Shivan Wumpus on top of its owner's library.
6/6

Kind of sucks that it can mess with your draws, but it does fit the theme of giving the opponent a choice.

I've always been a fan of tribal decks. A few things to note though:

The p/t boost and lifelink from Heron's Grace Champion is only temporary (except its own lifelink). Wilt-Leaf Liege's p/t boost is active as long as it remains on the battlefield.

I'm not sold on Phyexian Metamorph; nor Student of Warfare. In the Student's case, it could be just because I haven't played with it, but the Level up effect only affects itself and you have to waste precious mana to level it up.

Ghostly Prison - Lowers the chance of you being attacked.
Ethereal Haze - Prevents damage from creatures for the turn, even outside of combat. I prefer this over Holy Day.
Paradox Haze - Gives enchanted player multiple upkeeps. Azor's Elocutors triggers in each of your upkeeps.
Mana Leak - Between this and Render Silent, I'd personally use Mana Leak because it costs {1}{U}; where Render Silent costs {W}{U}{U}.

If you don't have money for the rare fetch lands, here's a few alternatives:
Evolving Wilds
Terramorphic Expanse
Bant Panorama
Esper Panorama

Also, Azorius Guildgate enters the battlefield tapped without giving you a bonus; nor do you have anything that cares for the land being a Gate, so I suggest removing it or replacing it with Sejiri Refuge or Tranquil Cove as they at least let you gain 1 life.

Zealous Conscripts - Just keep gaining control of Kiki to untap him; allowing you to create as many copies of Zealous Conscripts as you want.

A splash of Green gives you access to more search options for the Urza lands, specifically Sylvan Scrying and Ancient Stirrings. Ancient Stirrings also doubles up as "Search" for almost anything in the deck.

I strongly suggest working in the search as you're not doing much in the first few turns unless you draw Expedition Map.

Except that this is not technically an infinite loop as it will end when the opponent either doesn't have cards left in his/her library or doesn't have life left to lose. When there's no more of either life or cards, the triggers will stop.

To be honest, I just want to use Auratog in Modern. Consistency and aggression came along for the ride.
