GreenGuy47 I just brought the deck back from retirement! I had converted it into a Selvala cEDH , but i hardly played it, and Omntah was my general and the deck has always been fun. I definitely like Monstrous Onslaught because creature board wipes in green are so hard to come by! Three Visits, yeah, I don't really feel like dropping 100+ on something I can't even get foil lol. I run so many dorks to get Omnath out turn 2 so I keep the ramp spells limited, but idk, that might change depending on how play testing goes this time around. I was considering Helix Pinnacle as a wincon I could flash in with Emergence Zone or Vedalken Orrery, or just have it out early game because people don't want to waste a removal spell on it in the early goings. I've had Nissa, Who Shakes the World on my radar since bringing the deck back....i like mana doublers :D I will definitely be testing out different stuff as I get this deck back up to snuff, thanks for the all suggestions and reminders of good green stuff ^__^

Hey, idk if this deck is still active but I thought I would recommend a few cards. First of all Monstrous Onslaught is a must for all Omnath decks as it will most of the time wipe just about all of your opponents creatures for only 5 mana. Elephant Grass can be good. Elvish Herder is a great trample giver. Three Visits is better than rampant growth if you have the money. Nissa, Who Shakes the World is basically vernal bloom 2.0. I think Doubling Cube needs back in and Helix Pinnacle wouldn't hurt either. Lifecrafter's Bestiary is great card draw. Sword of Feast and Famine untaps your lands and gives you protection from a cast down or walk the plank. Crop Rotation is great with rogues passage and the cradle. Plow Under absolutely kills someone usually. Calming Verse is a one sided enchantment wipe, and Sylvan Tutor is wordly tutors weak cousin.

Nice deck!

I would like to recommend Monstrous Onslaught it wrecks everybody else's board if you have a big Omnath and then you have a few turns to take cheap shots at them. check out my deck for more cards!

Thanks for the input! After thinking about Blightsteel Colossus being in the deck I threw both Grafted Exoskeleton and Triumph of the Hordes in. What the hell. I like the idea of Steel Hellkite replacing Impervious Greatwurm but am saddened, as it is a really BIG green stompy. Utility > stompy though. Out are Endless Atlas and Basilisk Collar.

Monstrous Onslaught is a thing? The words 'as you cast' are beautiful; Phytotitan does not return to the battlefield at the beginning of my upkeep, or at all, really. Other suggestions you made were great and were able to find homes, with Llanowar Tribe replacing Yavimaya Elder, Return of the Wildspeaker in for Soul's Majesty and Steel Hellkite steps up for the non-Impervious Greatwurm.

Aspect of Mongoose in instead of Mortal's Resolve as more durable protection

Looking forward to the next game. And looking for a new home for Impervious G.

I think that you should run the Grafted Exoskeleton anyway. The hisses from the people at your LGS is just a sign of fear and weakness. Destroy them. ;P

Honestly though, if you were to run it you would be running infect in one of the most fair ways possible. You aren't even running Triumph of the Hordes. Since you are swinging with large creatures anyway, giving them infect isn't that much different from giving them double-strike. Infect gets an undue amount of hate because even though it isn't an overly strong strategy in EDH people just don't like being the first person knocked out of the game early because of infect damage.

That aside, I think that if you were looking to tinker with your deck more it would be worth looking at including copies of Llanowar Tribe, Overgrowth, Return of the Wildspeaker, Steel Hellkite, and Monstrous Onslaught. Each of them costs less than $1(USD).

Looking at your deck, it is basically just looking to play removal and ramp spells until it gets to at least 6 mana, then drop its commander or some other large creature. Although the deck does want to have as many lands out as possible for Multani, the quicker you can hit that 6 mana mark the faster your deck can start putting down what it needs to start pressuring the board. I've found that Llanowar Tribe is really effective at doing that in mono-green. Being able to go from three mana on turn 3 to hopefully seven mana on turn 4 would really help give your deck some wings. Overgrowth is another option for helping you hit that 6 mana mark quickly. Sol Ring and Thran Dynamo would also be worthwhile considerations. I know your deck prefers ramp spells that pull lands from your deck, but you have to weigh that against more efficient ramp that lets your deck play the game it wants to more quickly.

Return of the Wildspeaker is a straight up improvement to Soul's Majesty. It's an instant and it doesn't target a specific creature, so it doesn't get fizzled if an opponent kills your largest creature out from under you when you cast it. You also don't have any humans in your deck, so the second option for the spell will pump every creature you have out.

It looks like you want all that ramping the deck does to have more meaning that to just cast and pump Multani, so I suspect that's why you have such large creatures at the top end of your mana curve. Something to consider though is that instead of just going big, have outlets that let you sink extra mana into helping you generate additional value. Steel Hellkite not only gives you a large, evasive attacker but you can also pay extra mana into it for additional attack power or to blow up an opponent's permanents. At 6 CMC it is also likely that you won't have it stuck in your hand for anywhere near as long as something like Impervious Greatwurm would be. Those large creature make being so ramp-centric feel more fun but they are also going to be dead cards in your hand for a good portion of the game, especially if they are in your opening hand.

Monstrous Onslaught is one of the few mass creature removal spells that green has access to, and it works great with a commander that is just going to keep getting bigger as the game goes on. A lot of opponents won't expect a mono-green deck to be able to clear out 3+ potential blockers before attacking, so it might let you kill an opponent that thought they were safe after leaving back a few creatures to defend with.

Anyway, if you do end up making some changes to the deck I hope my suggestions help give you some ideas. Best of luck in your games!

This is not bad at all. I have a couple of suggestions off the top of my mind though...

-----Organization-----

First off, I highly recommend using custom tags to sort your cards. To do this, go into the "edit" mode where you can see your card list. It will look something like:

1xArbor Elf

1xBeast Within

1xShared Summons

You can then add tags by using #Category after a card. For example:

1xArbor Elf #Ramp

This will assign Arbor Elf to the "Ramp" category. Unsorted cards are assigned to "Other" by default.

I recommend these categories;

  • Ramp (Aim for 12-16 of these. A card that costs more than 4 mana is too slow to be reliably called Ramp)
  • Draw (At least 12)
  • Removal (Around 8, make sure you can deal with other commanders/creatures!!!)
  • Sweepers (Boardwipes, Green doesn't really have many it's okay)
  • Support (Stuff that isn't obviously powerful but makes certain cards in the deck busted. Examples are your equipment)
  • Lands (Obviously. Aim for 34-37. This deck wants 34-36)

The remaining cards can be categorized based on the specific inner-workings of your deck. For example, this deck might have a "Big Bois" category for creatures that are just huge.

Depending on your sorting preferences, it can by okay to tag one creature with multiple tags. For example;

1x Thorn Mammoth #Removal #Big_Boi

Onto my Card Suggestions:

-----Suggestions-----

Onto the cards I would suggest cutting:

-----Cuts-----

  • Elixir of Immortality . Your deck doesn't ever want to be in a game where this utility would be useful. This card simply doesn't do much. You already have Eternal Witness and if you really want a late-game reload, try Creeping Renaissance or Seasons Past .
  • Gigantosaurus is alright, but I'm not in love with a 10/10 with no abilities. I know, I know, he makes Ghalta cost only 2, but I still think there are better options. Trust me when I say a creature with some sort of utility is preferable here. Ideas include the aforementioned Soul of the Harvest , Primordial Sage or a fight creature such as Thorn Mammoth or even another removal creature like Woodfall Primus or Terastodon (sorry, I know these are all really high CMC). Generally, cards that don't have some sort of utility are just not going to save your life when things get ugly.
  • New Horizons and Gift of Paradise could be replaced with faster ramp. For the sake of having creatures (for cards like Guardian Project and Beast Whisperer , not to mention Ghalta, Primal Hunger ), it would even be better to run Wood Elves , Springbloom Druid , Yavimaya Dryad , or Farhaven Elf .
  • Diamond Mare just isn't relevant. Sorry, but if you are in a position where gaining a small amount of life matters, odds are any other good green card would have done more to prevent you from being in such a bad spot. Your deck wants to be the aggressor, and quite honestly your offense will be so scary that most opponents wouldn't even consider attack out of fear of provoking you and simultaneously tapping their defenders. It isn't uncommon for a Green deck to retain the highest life total for a long time without the need for lifegain.
  • I think you have a few too many artifacts. Remember that your commander LOVES having creatures on the field, so finding ways to turn your artifact utility into creature utility will go far.
  • Staff of Nin is very slow and could be something like Garruk's Packleader instead.

-----Conclusion-----

All things considered, you've got a reasonably strong lineup. In a broad sense, I would recommend finding ways to include creatures with utility, since Ghalta appreciates bodies on the board and interaction allows you to curb your opponents' shenanigans as much as possible. Additionally and as I noted, there are fairly budget-friendly ramp options for the deck that are purely faster. Remember to keep a close eye on your Ramp and Draw, as these are the lifeblood of a commander deck, midrange especially.

It is worth mentioning that I never go below 34 lands. 35, and 36 are usually safe, so if you find yourself land-starved just add like 2 Forests and that should help.

Overall, you've done a good job though. Good luck making edits and please feel free to contact me about further changes/advice. I LOVE deckbuilding and Green is one of my colors ;)

I love Grothama and power matters decks. I run a Multani-Maro Sorcerer deck myself :). Here are some tips for cards you could consider:

However, all in all it looks great! These are just some cards you could consider :).
