This deck looks absolutely silly and fun and I love it. +1

Thank you. Any advice on the sideboard? I'm not sure I'm feeling it in the current configuration.

I sadly have no knowledge on Standard at the moment, so sideboard help from me wouldn't be that great lol

I suggest adding Hangarback Walker as your win con. A 15/15 creature that can create creatures sounds pretty sweet.

Only problem is, the Hangarback doesn't have haste (though not having haste is not a disqualifier in itself), and the thopters can be Languished away. I need something that hits, stays, and doesn't have interference. Gaea's Revenge is good, Pearl Lake Ancient would also be good if I was in those colors. I appreciate the suggestion, though. Anything else you got?

Haste is going to be challenging in these colors. There's a lot of big, fat hydras from Theros you could use: Hydra Broodmaster would be funny. Maybe consider those as a holdover until we see what's in BFZ?

Yeah, I can appreciate that, Jim... not impossible to find, though. Gaea's Revenge is an option. I just realized that Meandering Towershell works in my favor, since I can cast The Great Aurora the same turn the Towershell comes back from exile tapped and attacking, so it might as well have Haste. Maybe not Broodmaster, I was considering Mistcutter Hydra

I've been thinking of a build like this. I was thinking I'd wait for Zendikar (ya know, just in case there ar some interesting effects involving land in Zendikar) and make it probably Christmas, with Zendikar Incarnate, Zendikar's Roil, Nissa, Vastwood Seer  ^Flip, and the pseudo- Scapeshift reprints that are The Great Aurora and Animist's Awakening just to get sheer power out of land.

These things you have done with the Great Turtle... This is wonderful.

Damnable Pact? splash blue for Villainous Wealth? Mistcutter Hydra is still in standard as is Colossus of Akros

I was toying around with Mistcutter, Papa. Colossus might work. Only downside of both of those things are things like Celestial Flare, Reality Shift (in the case of the Colossus, anyway), and Aetherspouts. Gaea's Revenge is at least a safe bet because A) can't be countered, B) has haste, and C) can't be the target of non-green spells or abilities. It's the critical mass of things I need in a game-ender. The turtle at least lets me attack on alternate turns between Aurora castings. Plus I can keep mana free for other game-ending creatures. I appreciate those suggestions, though.

Non-targeted removal still hits Gaea's Revenge. Aetherspouts will get it, for instance.

Yeah, as will boardwipes, same thing for all that other stuff. Ugin hoses this deck fierce if you've only got 1 game-ender in hand. That's why Pearl-Lake is pretty tempting. Plus flash is pseudo-haste. The only thing that works in my favor is how frequently my opponent is off-color for double cost anything. Between taplands and lifelands, I'm usually fine for 1, maybe 2 turns. If it drags past that, I've gotta close another Aurora or call it done. I am aware of the non-targeted clause. Only thing is, those are usually sorcery-speed spells so I'm frequently safe.

As an aside, I explicitly added green to my deck simply for a playset of Sultai Charm since it is an instant that targets and kills Gaea's Revenge. There are plenty of ways to kill it. Honestly, with all these mangoes, Rakshasa Deathdealer might be immensely good an functional.

I'm sorry, I meant Rakshasa Deathdealer

I dig the altart.

Literally just spent 10 minutes playtesting. That thing is a blast. Thanks for sharing. I tried to do something similar after KTK and Fate rotated out. Land spam spells with Zendikar Resurgent, using The Great Aurora to establish superior board presence and a fireball spell to hit my opponent's face.

Thanks TMBRLZ. Like I said, I'm still working on a workable Modern solution... sort of like a budget scapeshift. But this is what worked for Standard.

Would be interested in what you come up with. I think I investigated a modern deck similarly following Origins rota, but got overwhelmed about the depth of options and then I'm pretty sure I somehow ended up getting sidetracked into making a rogue deck (creature type rogue).

Gatherer is a scary place.

Yeah, this looks crazy fun. I'll be happy to see what you do with it.

Hey TMBRLZ, check this new build out.

I like where you're headed but it seems clunky. First issue is your mana is too even. A few playtests found myself sorely missing sources. use the mana chart and adjust accordingly. You should consider more shocklands - Breeding Pool + Overgrown Tomb as they'll count as "forest" types for your Utopia Sprawl to land on and can enable you to hit either as well as your colors.

Wasn't sure how I felt about a spell heavy variant cause it lowers the number of permanents in play, but the Memory could be a good way around that. Your only follow up issue is the lack of an alternate wincon. You lose to Leyline of Sanctity. You could also consider lowering the land count. You've got more protection like the Commit and Perilous Vault and Cyclonic Rift when really you should just jam out as hard as you can imho. Consider more big stompy, preferably ones that benefit based off of lands like Ulvenwald Hydra (there are some better Modern alternatives I don't know off hand).

Consider less lands, a more balanced mana base, some creature win-con as backup, and maybe some man-lands as well. Slower mana but nice alternate beats that can be hard to target.

Just needs to build a bit faster and be more straightforward for the kind of speed we're looking for with the card advantage of The Great Aurora. Definitely on the right track though.

Yeah I actually don't put as much money into my MtGO lists as I put into my real-life deck, this was pulled from that. Shocklands would be a thing. Also, between Commit and Cyclonic Rift, you don't lose to Leyline, because you put it back in their hand. 30 lands is how you maximize the positive results from Great Aurora. If you draw 15 cards and they draw 15 cards, they'll get, on average, four lands. You get, on average, 8. You're in better shape than they are. If I did change it to make it slightly creature-centric, I'd probably do 4 Coiling Oracles, 4 Sylvan Caryatids, and 3 Ulvenwald Hydras or Primeval Titans. Another possibility is 4x Coiling Oracles, 4x Coursers, 4x Cryptolith Rites and then non-Wealth game-enders.

Oh, and also, Perilous Vault also hits Leyline

I wouldn't be mainboarding Leyline responses though. Mainboard for a combo deck should be all drive and no brakes in my opinion. Save the counter tech for the side. No use in main deck defending against a card that 90% of players won't have until game 2.

They're not Leyline responses, they're board state responses. It's just that it's a board state response that's really good whether it's primary or sideboard. Same thing for Cyclonic Rift and Commit.
