It is not an artifacts deck so I don't really see the point of using Lodestone here.
It is not a real threat and will just needlessly tax your own spells.
This list is pretty bad, it tries to be a midrange-ponza hybrid with 4x Huntmaster and 4x T.Tracker which aren't bad but shouldn't take that many slots in the deck especially over PW's like Chandra (or Garruk).
It might be a decent card against control decks as it can close out games faster than Thrun but it is vulnerable to sweepers (but better against chump blockers).
Congrats on the finish, the deck looks pretty solid though seeing Manamorphose here is pretty jarring.
I'd rather have Tireless Tracker (draws cards and is a secondary threat) or Courser of Kruphix (blocks, gains life, survives anger) instead.
Also maindeck L.Bolt seems not terrible and frees you 3x extra SB slots (Beast Within is very good with GDD).
I did a quick search and didn't see it brought up, but has anyone looked at replacing red with black? You lose Blood Moon (which is obviously bad), but you have a functional (albeit harder to cast) replacement for Stone Rain in Rain of Tears and gain direct (and better) removal/better card advantage/a different set of threats (Think Abrupt Decay, Fatal Push, Grim Flayer, Liliana of the Veil, and a more black/color fixing list could even try to run Phyrexian Obliterator)
I love my GR deck, but would be interested in doing some testing. You can even keep it low to the ground like the older Growza decks with Tarmogoyf/Grim Flayer or have a more overall land based deck with Courser of Kruphix/The Gitrog Monster. Obviously not trying to derail the thread and turn it into a GBx Rock conversation, but would a ponza-style deck with MWAM minus red have merit? Is it even worth talking about?
I don't think it is a great idea as it doesn't work with the Utopia Sprawl plan and is terrible outside of having it in your opening hand on the draw (and having to exile a card).
Having 10x turn 1 ramp cards is enough imho and if you want even more you can add Birds of Paradise 3-4.
I'd also cut one of the creatures for Primal Command, probably Hazoret.
If you don't have a good PW for card advantage (Nissa, Vital Force is pretty cheap) even a copy of Harmonize isn't too bad.
The birds are a necessary evil imho, the deck absolutely needs the turn 1 ramp (I'd mulligan most hands without it)
and is very slow and clunky otherwise.
Also, wouldn't Obstinate Baloth (also good against discard) be a more efficient stabilization creature against aggro/burn over Thragtusk ?
The 5-drop slot is also rather cloged with the 2x Stormbreath, 2x Garruk and 1x Primal Command already.
Strangely enough the deck runs only 8x turn-1 acceleration pieces (no 2x Birds of Paradise) and 22x lands instead of 21x.
2. This is probably an easy match-up, they have no pressure whatsoever and are weak to LD, Beast Within (and Stormbreath Dragon) is very good against any of their PW's.
An early Chalice of the Void can be annoying but not that bad. Flashfires is really narrow but might work too.
It is not a real threat and will just needlessly tax your own spells.
It is like suggesting Thalia to U/W Control.
Crumble to Dust is a pretty bad option as well, should be Beast Within or Molten Rain instead.
Dragonlord Atarka isn't bad but Inferno Titan is just better and easier to cast on time.
I've never like Acidic Slime in the maindeck (maybe as 1x-of in the SB) and having both Thragtusk and Wurmcoil Engine is too much and I'd cut one of them as well for a Primal Command.
I'd rather have Tireless Tracker (draws cards and is a secondary threat) or Courser of Kruphix (blocks, gains life, survives anger) instead.
Also maindeck L.Bolt seems not terrible and frees you 3x extra SB slots (Beast Within is very good with GDD).
Maindeck Chandra, Thrun or Obstinate Baloth don't sound too bad either.
Black isn't a good color for LD (unless we get Sinkhole), you can go GB with Death Cloud/Smallpox but it will be a different deck.
Red is miles better for this strategy.
Having 10x turn 1 ramp cards is enough imho and if you want even more you can add Birds of Paradise 3-4.
It is just outclassed by Thrun (which isn't that good in the deck outside of control matchups anyway).
It also doesn't have evasion.
I'd also cut one of the creatures for Primal Command, probably Hazoret.
If you don't have a good PW for card advantage (Nissa, Vital Force is pretty cheap) even a copy of Harmonize isn't too bad.

I'm not sure about Garruk, Primal Hunter over Nissa, Vital Force (which is the better PW imho) though.

Ancient Grudge or Shattering Spree/By Force/Vandalblast should be good.
#Ruric Thar, the Unbowed can wreck any combo deck and Beast Within deals with Phyrexian Unlife.
#If they go for the Laboratory Maniac kill Sudden Shock can get them (through Pact of Negation).

Flashfires is really narrow but might work too.
3. Against these decks Thrun, the Last Troll is probably your best card, also cards like Ricochet Trap/Guttural Response (or Vexing Shusher) can help against counterspells.
Trinisphere/Defense Grid (and Ruric Thar, the Unbowed if you can resolve him) can be pretty good here as well.
There is also Choke but it seems unnecessary with Blood Moon.
#Lignify is probably worse than more copies of Beast Within or just Roast.
#Cards like Thrun, the Last Troll and Chameleon Colossus make Great Sable Stag irrelevant.
#Genju of the Spires is bad, Kessig Wolf Run can be used to turn any mana dork into a threat.
