Helix Pinnacle can not be targeted by Gilder Bairn's doubling effect as it has shroud.

Bogardan Hellkite is everyone's go-to dragon for Dragonstorm, but my favourite dragon to storm into is Kokusho, the Evening Star. It's death trigger causes life loss, which can't be prevented like Bogardan Hellkite's damage. I use the legend rule to kill Kokusho, and the way it currently stands forces me to keep 1 Kokusho and not get its death trigger, but that's why I also run Predator Dragon, so I can devour that last Kokusho :p

I'm sad that Seething Song is banned in Modern :'(

Endless Ranks of the Dead + Paradox Haze :p

And to a lesser Degree: Jace's Erasure

With Ghostly Prison and Sphere of Safety making them pay mana to attack, Mesmeric Orb can help mill faster. Orb of Dreams / Frozen Æther causes everyone's / the opponent's stuff to enter the battlefield tapped, making Mesmeric Orb more potent. You're already running Wheel of Sun and Moon, which I'm guessing is to stop self mill, so Mesmeric Orb's down side isn't so bad (though I'd bump Wheel of Sun and Moon up to 3x)

I wouldn't say that the site is broken, because only BfZ stuff doesn't show colour.

Converge works similarly to Domain from Conflux, so I suggest looking into some of those cards.

I wouldn't say that the site is broken, because only BfZ stuff doesn't show colour.

I only now realise that Mwonvuli Acid-Moss lets you search for any forest, not just a basic forest. Ravnica duels and the new Zendikar duals would work nicely with it... well, the forest duals anyway.

There, edited it to include Stronghold Discipline

Except that sphinx's tutelage is completely out of colour.

Because the opponent's get to use Howling Mine's / Rites of Flourishing's effects first, one option is just waiting them out with a slow mill. The other option here is to make them lose life every time they attack via Hissing Miasma and Batwing Brume. I'm also trying to figure out which fog to reduce / remove to include Stronghold Discipline so I can close off the game after giving enough creatures with Forbidden Orchard.

So, in short, a number of passive ways.

Also, Shrine of Loyal Legions doesn't fit in with some of what I suggested, so that's another possible drop for something.

Nykthos, Shrine to Nyx would help play some of those more expensive creatures and supply more mana for Secure the Wastes.
Honour of the Pure and Intangible Virtue will help all your tokens get bigger.
Heliod, God of the Sun's token making ability is another good card to dump excess mana into, especially if you include Nykthos.
Spear of Heliod is another good pump for all those tokens and it's has a great reactive removal effect.

Fun little trick I'd like to try with Undead Alchemist is Undercity Informer. Sac a creature to Undercity Informer, then any creatures that are milled get exiled due to Undead Alchemist's ability, giving you more creatures to sacrifice to Undercity Informer :p Sadly, I don't have either Undead Alchemist nor Undercity Informer :(

*Reads Explosive Vegetation again* o.0
I've been playing it wrong, and no one pointed it out to me... I always thought Explosive Vegetation was just a more expensive Cultivate / Kodama's Reach.

Nissa's Pilgrimage is better than Explosive Vegetation in here. Your only basic lands are forests after all.

While both aren't bad, neither solve the problem. I need to play Nissa's Pilgrimage on turn 2.

Honored Hierarch needs to become renowned before being able to tap for mana, which means, at earliest, he attacked on turn 2 and is tapped, so I can only use the mana on turn 3.

While Beastcaller Savant has haste, there's two problems with it. Firstly, you have to pay 2 for it, which basically leaves you with 1 mana (it's ability) on turn 2. Secondly, "Spend this mana only to cast a creature spell." which doesn't allow me to play 15 of my cards.

And in both cases, the "any colour mana" means nothing as this deck is mono green.

I'm going with Whisperer of the Wilds. It allows me to not have to target it with Sandsteppe Mastodon's Bolster if Elvish Visionary isn't around and I have Elemental tokens; AND it nets me more mana when I have a big creature out.

I'd strongly suggest Surgical Extraction. After a bit of milling or a Inquisition of Kozilek, it is better than Cranial Extraction. It can also target non basic lands, which makes Sphinx's Tutelage (suggested above) and Mind Funeral (another VERY good mill card) much better.

Why not both?
