Love this deck. Thromok is soooo awesome. Did you consider Kazuul, Tyrant of the Cliffs ? +1 from me.

How many tokens have you sacked to thromak? Awesome deck +1

in test play i sacked 6400 token with doublin season giving him like 73 million counters

pretty cool! +1

how about Warstorm Surge ?

Feed the Pack could do well with this deck, a friend of mine has a thromok devour deck and uses this to make thromok a 100000/100000 due to so many wolves devouring him the first time then he devours the wolves the second time he summons him.

you may also consider playing Brawn for giving your creatures trample, as Bramblewood Paragon is a bit fragile. Blasphemous Act would also be a good mass remover for this deck. card:Soul's Fire could also be quite practical

Anger and Genesis could also be quite useful to you...

Fling

I love Feed the Pack makes more wolves that you can devour and will master of the wild hunt omg crazy

Please look at my deck Card Cycle of Devastation

One bad thing is that Thromok the Insatiable does not have Trample.

And to a good Murder

No Awakening Zone ? And to a lesser extent, Goblin Assault . I also like Predatory Advantage , but I understand it not being up to snuff. Something I think you absolutely should consider though: Rapacious One . +1 from me! I think I'm going to build myself a Thromok deck as well!

Triumph of the Hordes could be a funny as hell and lethal finisher. Vivid Crag , Vivid Grove for easy mana fixing if it arises. Sapseep Forest and Madblind Mountain or Kessig Wolf Run or Skarrg, the Rage Pits utility lands are always good. Terramorphic Expanse with your Evolving Wilds helps thin your library. Stomping Ground and fetch lands if you're able. Tooth and Nail /Reap and Sow ? Beacon of Creation ? +1 from me

Use Surestrike Trident . It's insane with your commander. You even don't need to attack to kill an opponent. Mage Slayer is pretty badass with him too.

In a deck like this that is fairly creature heavy, Domri Rade just for the heck of it would be hilarious.

You might like Decimate & Gruul Ragebeast .

Stomping Grounds, Taiga, Wooded Foothills, Krosan Grip, Skyshroud Claim, Vorinclex, Voice of Hunger, Urabrask the Hidden, Praetor's Council, Banefire, Green Sun's Zenith, Survival of the Fittest, Beast Within, Woodfall Primus, Birthing Pod

Have you thought about including Pandemonium as well? Gives a bit of redundancy for Warstrom.

Also Goblin Bombardment seems a good way to use tokens that you can't get around to Sac, as well as a good way to fight board wipes.

I think you should consider:

• Avenger of Zendikar = a creature that can makes an army that you can either use to devour or smack face.
• Awakening Zone = devour fodder or even be used as a form of mana ramp.
• Conjurer's Closet = you have creatures with ETB effects, why not reuse them?
• Cultivate = IMO mana ramping is way better in the long run, plus it thins out your deck of those lands. This helps with better card draws in the future, and are also less vulnerable than creatures like Birds of Paradise
• Kodama's Reach = same as above.
• Skullclamp = you have lots of tokens, draw advantage is very powerful.
• Nim Deathmantle = give whatever creature you want another fighting chance. Can be very abusable with sac outlets.
• Godo, Bandit Warlord = if you decide to run atleast 3 equipment, I believe this guy is just awesome.
• Asceticism = protect your creatures.
• Mimic Vat = creates a token of whatever you want that hits a graveyard. Very powerful card to have.
• Terastodon = I noticed you don't have any artifact/enchantment hate. Against my control deck, you would have such a hard time to get damage through. Plus it puts in elephant tokens :D
• Acidic Slime = Just another artifact/enchantment hate suggestion.
• Ground Seal = you deck doesn't seem to interact with your graveyard a lot. This just helps against black decks using your big creatures on you.
• Ooze Flux = I noticed you have lots of counters everywhere. This just gives you an option to reuses those counters so they can be redevoured again or for a giant beast. This also makes your opponents think and play differently on how to get rid of your giant general or another creature with lots of counters.

Well hope this helps. If you have the time, come check out some of my EDH decks and let me know what you think. :D

Why aren't you playing Overwhelming Stampede?

Actually, the bigger question is why aren't Kessig Wolf Run and Skarrg, the Rage Pits in there.

If you're going to run Warstorm Surge and Pandemonium , why not Sekki, Seasons' Guide ? Entirely on theme and combos for infinite damage.

Also, Artifact Mutation and Snake Basket

Just thinking outloud, but after playtesting a bit it seems that you have a lot of devour creatures and not a whole load of token engines when really you should focus of getting your commander out and dealing petty damage with an army of tokens.
