Hey! The deck looks good :) but a few small suggestions:

Things I might add: Good draw (Phyrexian Arena, Necropotence), extra combats, good removal, better acceleration/fixing (see below; Urborg, Tomb of Yawgmoth).

Keen Sense, Sixth Sense, Sword of Feast and Famine and friends, Bedlam, Malicious Affliction, Seize the Day, Relentless Assault, Aggravated Assault, Mana Vault, Golgari Signet and friends, Coalition Relic, Chromatic Lantern, Mana Crypt...

...cont

...the fetches/shocks if you want a strong landbase, Earthcraft, Berserkers' Onslaught, Domri Rade, Rage Reflection, Toxic Deluge, Bloom Tender, Crux of Fate, Vampiric Tutor, Demonic Tutor, Parallel Lives, Kodama's Reach, Cultivate, Skyshroud Claim (going for basic-typed duals like Stomping Ground etc), Ranger's Path, Sylvan Library, et cetera...

Final suggestions: Mana Echoes seems pretty odd here - how does it work? Id also put way more info in the description, and use Ogre Battledriver over Madrush Cyclops. Finally, Mana Vault really does need to be in there ;)

Ooh. You could use Aggravated Assault for the infinite combo with Sword of Feast and Famine/Bear Umbra. And you could use Archfiend of Depravity to make that sacrifice effect HURT.

Omg Daedalus19876 that's such a good idea, I never thought of that!!!

Keen Sense is almost strictly better than Sixth Sense, btw. (And has better art.)

Why Daedalus19876? They seem relatively the same.

Keen Sense works REALLY really well with Harsh Mentor, Scourge of Valkas, and Purphoros, God of the Forge (if they're creatures).

Possibly Worldly Tutor over Impact Tremors?

Personally, I'd cut Rampant Growth, Strionic Resonator, and One with Nature. I'm sure you have a long list of cards to replace them.

I agree with rampant and one with nature but now sure about strionic yet I have to test it more.

I vote for Hellkite Charger and Bear Umbra. With your commander and these two, you can sweep your opponent's whole board and then create all the toothless babies you wannt.

Lands to stabilize your land base: Karplusan Forest, Llanowar Wastes, Sulfurous Springs, Savage Lands, Stomping grounds, Overgrown Tomb, Blood Crypt, Reflecting Pool, Exotic Orchard, City of Brass, Mana Confluence, Forbidden Orchard, Rakdos Carnarium, Gruul Turf, and Golgari Rot Farm.

I would suggest adding in some more Tutors (e.g. Worldly Tutor) to make your desired combos far more easy to pull off, while at the same time I would suggest adding some cards such as Crawlspace to bolster your defences, otherwise this could easily prove too one-dimensional in a multiplayer format (something that I personally feel is often a fundamental flaw of Voltron decks). Also,Berserkers' Onslaught is much, much better than Blood Mist, and Gratuitous Violence is another good option that covers similar ground.Other than that, I personally feel that Xenagos, the Reveler is better than Domri Rade, but both do similar things.Also, while you may not get the devotion for him at any point, Xenagos, God of Revels seems like it would be a perfect addition to this deck, possibly in place of Ivy Lane Denizen, which I cannot see having sufficient impact in a packed multiplayer format.

+1 for first the line of the Description.

Also because Dragons are the greatest.

Thanks seshiro_of_the_orochi I think aggregated assault does the same thing but I'm seriously thinking about Hellkite Charger. And Daedalus19876 I'll take a look at that land base later. I agree mine needs to be more stable.

Thanks for the suggestion nap Atavistic. I agree Ivy Lane Denizen was a card left over from the first draft when I misread my commander and thought she said sac And get a cat. That card does need to go. Worldly is a great suggestion as is Berserkers' Onslaught. I like adding xenagos but I think I'll keep Domri for now. Thanks for all the great advise!

Lol thanks Argy I like the quote and meme too haha :)

thats not a legendary creature/ most of the cards arent in the color identity???? please elaborate

never mind, sorry

Lol Olivia_bigelow no problem. As stated in the description, sadly, unofficial spoilers are no longer allowed on the site and posting descriptions or pictures of them can get you banned :/ Thanks for checking out the deck

Cat Dragon is best creature type!

Casey4321 I 1000% agree!!

Atarka, World Render? Dragonspeaker Shaman?

Ceral: Dragonspeaker seems somewhat shaky - are there enough dragons here?

OOH OOH Utvara Hellkite !

Ceral I like the idea of Atarka, World Render I need more double strike. Thanks :)

Omg Casey4321 I can't believe I missed that thanks!!!
