Okay, so Epicurus's challenge looks unfinished,

House of Leaves

Legendary Land

House of Leaves enters the battlefield tapped unless you control a Dryad.

: Add .

, : Untap target Dryad you control, it gains shroud until end of turn.

Okay, so Destroyerbirb's challenge was for

"Make the biggest creature in magic with no downsides other than it's mana cost for Ikoria, Lair of Behemoths."

Impervious Greatwurm is the largest printed card and Dark Depths produces the largest token.

So, at least a 16/16

Impervious Greatwurm could be a possible inclusion if you were to build a reanimator version of Jarad, Golgari Lich Lord. Ikoria is giving us Titanoth Rex and Void Beckoner, which are both big bodies that can send themselves to the graveyard for cheap. Dump your big creatures to the graveyard, reanimate them, and then if they are about to die just sac them to Jarad to hit your opponents for a ton of damage. Then reanimate them again. ;P

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!

Nissa, Who Shakes the World is good. I would cut 2 Gaea's Revenge for 2 of her. Also maybe cut 1 Impervious Greatwurm for a Gigantosaurus . Neat deck. Stomp on my green brother
