Any reason you're running Harrow over Crop Rotation? Besides the holy shit pricetag on a foil that is lol. It just does the job better and is essentially Gaea's Cradle #2.

What I would take out: Tireless Tracker because it costs too much to sac the clues.

What I would add in: Zhur-Taa Ancient, Sword of the Animist, Wayward Swordtooth, Zendikar Resurgent, and Traverse the Outlands are all good ramps. Lurking Predators is a personal favorite. If your facing a counter deck then Prowling Serpopard is great. And last but not least Legion Loyalist. Legion Loyalist is only good if your deck is attack-oriented (which i'm pretty sure it is) All in all +1 on your deck!

So, I've been having some difficulties finding some of the cards in this list, so these are my preliminary subsitutions:

Subterranean Tremors -> Blasphemous Act

Tooth and Nail -> Defense of the Heart

Heroic Intervention -> Eldrazi Monument

Storm Cauldron ->

Mind's Eye -> Cream of the Crop

Nissa, Vital Force -> Nissa, Worldwaker

Wheel of Fortune -> Reforge the Soul

I'm also looking at a slot for Groundskeeper since it'l be our third method of mass land retrieval.

Last_Laugh, I use Harrow over Crop Rotation, mostly for early ramp and landfall triggers with Lotus Cobra and the big guy. Crop Rotation isn't very beneficial for me early game to grab Gaea's Cradle, since most of the time, I don't have creatures on my board until Omnath is out.

JoeBob21, once mid game rolls around, it becomes easy to take advantage of Tireless Tracker and the clue toll. As for the suggested cards, I don't have the spots to include them. Nonetheless, they are great cards and most of them have been in a previous build of mine. Thank you for your suggestions and thanks for the +1, I appreciate both!

feyn_do_alduin, I believe those are great substitutions. They still keep the theme intact. I would substitute Storm Cauldron for maybe a Blood Moon, Magus of the Moon or Stranglehold. If you want to include Groundskeeper, I would replace Manabond, since it was included mostly to pair with Storm Cauldron.

Love the deck. I use the same Commander and I have my build posted on this site too.

Since my playgroup isn't as oppressive, I run a "friendlier" version of your deck. That said, I've been wondering why Prismatic Omen isn't in your deck. Also, Zendikar's Roil ups the number of sacrificable Elementals too.

I can think of a few more cards, but I'll wait for your response to my previous ones.

Look into Tilonalli's Summoner. I have won a few games now with him and Omnath on the board. Especially when I get Goblin Bombardment

Rymnas, I wish I had better reasoning for why I dont run Prismatic Omen, other than Ive never felt it necessary to include. I dont really need color fixing with a two colored commander.

I use to run Zendikar's Roil in my retired, traditional Omnath build. It just didnt make the cut when I switched to a MLD Omnath build. Zendikar's Roil is a good card, I just dont do as much token production and sacrificing them this time around.

immortaljackwest, I like the idea of Tilonalli's Summoner and I have thought of including it before. I just dont run any haste enablers or protection to justify adding the card. Its too squishy for my playgroup and would be dealt with on my board before I could activate the ability. If I ever decide to switch back to my traditional Omnath build, I would definitely give it a shot. It would fit much better there.

Why not use cards like Naya panorama.

Mythrandir only fetches basics that ETB tapped

Prismatic Omen isn't used for mana fixing, it's used for valakut kills

Looks like I must have overlooked that aspect of Valakut, the Molten Pinnacle and Prismatic Omen having great synergy together. Now it makes much more sense why it should be included. I might give it a try after all. Thanks for clearing that up, PhyrexiaUnleashed.

You could consider [Strip Mine], you have crucible of worlds so it becomes a never ending cycle of destroy target land, sac it, replay it, destroy another land, sac it etc etc. I run it in my [Numot, the Devastator] land destruction commander deck. It is basically a win-con in 1v1...

Still new on this forum, Strip Mine and Numot, the Devastator

oh shit, you already have it.. my bad lol

Suckiest deck ever kid!

magicthegatheringplayer37, come on now, it cant suck that bad, it still rocked your world and now youre crying about it lol

I'm just kidding and being funny. It is actually a pretty good deck. LOL! XD :)

magicthegatheringplayer37, I was poking at some fun too, lol. A little fun fact, this build is actually banned within my playgroup. So for laughs, I showed my group your comment and I told them, See this build sucks, so I should be able to play it again. Then they replied, Yeah, it really sucks to play against. Nice try, but NO! Well, so much for getting my hopes up high and thinking Id be able to bring it back to the group. Oh well, I suppose. There is always the LGS...

I like the new updates! the only one i find questionable is War's Toll since it would, in my playgroup anyway, draw an insane amount of heat to ourselves.

feyn_do_alduin, I am on the fence with War's Toll myself. I thought I would give it a try since I have had success with it in my Ruric Thar, the Unbowed deck. Another option I was looking at for that slot was Citadel of Pain. I am open to suggestions to replace War's Toll if there is anything that would be a better fit for controlling the controlling. Let me know what you think.

Citadel of Pain is far more like it for a counter control/resource control deck like this.

as far as alternatives/additions go; Adventurous Impulse, Broken Bond, Song of Freyalise (I have a foil, it's pretty af) , Sylvan Awakening, Damping Sphere, Helm of the Host (well worth a slot IMO), Memorial to Unity are ALL worth some serious consideration.

My top considerations would be sylvan awakening, helm of the host, and damping sphere.

Sylvan awakening should be obvious, helm gives mo 'nath lovin to go around (turns 3 damage into 12 after a single use with 4 damage instances off a single land drop and delegendized copy), and with this deck's tempo being often slow I feel that we should add another tax/tax-like effect to slow our opponents.

feyn_do_alduin, the new Dominaria set has provided Omnath with tons of fun options. Though Helm of the Host is the card Id like the most to include. Ill most likely remove War's Toll for it. Thanks for your input!

Just an idea, I am adding Command Beacon to mine. That along with Burgeoning is going to make for a killer possible opening hand

immortaljackwest, those two are good additions. I use to run both, but moved on from them at some point. Dont forget to include Ghost Town to pair with that Burgeoning if you havent already.

What decks do you go go against, Choke, Carpet of Flowers, Tsunami, Boil, Boiling Seas, Flashfires, Omen of Fire and Ruination are all good options depending on the group, and Magus of the Moon, Blood Moon, Blood Sun are also great cards
