[Standard] G/R Monsters Evolution!

Obviously the deck is relatively good for you to have performed so well this past weekend.  But, that being said I think there are a few areas for improvement.

First off, this certainly isn't like the G/R devotion list that is in need of a crap-ton of mana to dump your entire hand every turn, so I wonder whether you need that ramp or whether perhaps you could use some of those spots for other cards.  Specifically, I like the Sylvan Caryatids as they offer blockers AND ramp, but Elvish Mystic strikes me as horribly under-performing for you.  That and a top decked mystic on anything other than the first 3 turns is just weak.

Personally, I like what you're doing with the Ghor-Clans and Flesh // Blood.  The idea that you can swing with Polukranos, pump him, and then still zap them for 9 more for only two more mana is quite appealing (hard to believe nobody else has noticed it).  So if you were to drop the mystics, I can see where adding two more Flesh // Blood and perhaps 2x more Bloodrush would be effective (I'm thinking either Rubblehulk or Zhur-taa Swine as they both lead to a substantial pump), although the trample from Ghor-Clan is really what makes it so good.  To that end, perhaps 2x Nylea, God of the Hunt could prove beneficial.

The only other area I can see for improvement is the SB.  The 4x Mistcutter make perfect sense and I'm good with that (although I would perhaps say to go down to 3x).   I'm not so sold on where Shock is going to be sided in and will make a difference.  Destructive Revelry is really misleading as I would likely run Fade into Antiquity over them - getting rid of Thassa or Nylea is a pretty big deal.  I'm also not sure I see a scenario where Chandra, Pyromaster would come in... as you're already generating card advantage with Garruk, Domri, and Xenagos.  So I can see a fair amount of wiggle room here to drop stuff and find pieces that will be more beneficial to your specific match-ups.  If I were to run with a SB for this deck it would likely look something like this:

2x Pithing Needle - stop Elspeth, Jace, Ashiok, Pack Rat, Mutavault, etc etc

3x Mistcutter Hydra - you know the mono-blue matchup

2x Plummet - a good call, as it will take out a Desecration Demon in a pinch

2x Fade into Antiquity - exiling, scrying, and just for one more than Revelry... yeah I'd do that

2x Bramblecrush - destroys PWs, artifacts, enchants, lands, you name it... this card is sort of a skeleton key

2x Mizzium Mortars - you could talk me into these being Anger of the Gods - your aggro matchup is a bit weak from what I can tell

2x Ruric Thar, the Unbowed - if you ever wanted an anti-control card, this guy is it... but you'll want 2x as you'll almost never draw him with only 1x OR, might want to draw 2x in long games

Anywhom, I hope some of this helps.  Props to ya for finding a different way to attack the R/G build.

Oh yeah, I almost forgot... if you want something else totally off the wall, I played against someone using Savageborn Hydra the other day and it was quite the nuisance.  Make even a 3/3 one and then the next turn swing, bloodrush Ghor-Clan on there, you'll hit for 14 and can cast Blood to do 21 damage in a single turn... some food for  thought...

Thanks for the feedback TyWooOneTime.  First off, I didn't build this list, Chris Van Meter with some help from Brian Braun Duin did, so the credit goes to them with regards to your overall assessment.

Elvish Mystic is definitely a card I'm looking at in this deck as being a possible cut.  However it and the Temple of Abandon or in certain situations Stomping Ground represent an 8(12) card count towards a value play on my first turn.  1/5 of the deck if you count them increasing my chance of starting with at least one of those cards. 

The Mystic also makes Turn 2 Domri Rade a possibility and very high value depending on the opponent and his board state and creatures.  If Domri isn't there Sylvan Caryatid on Turn 2 can turn into a Turn 3 Polukranos or Stormbreath Dragon.  This happened quite a lot, and put opponents on a short clock if they can't deal with the threats. 

That being said, top decking a Elvish Mystic on turn 5 or 6 is usually a huge disappointment except in a few circumstances where the extra mana the next turn helps Polukranos or Stormbreath Dragon do monstrosity for good profit.  I might cut him and test for a bit and see how it goes though. 

Flesh // Blood is awesome.  I want to run more but every non-creature limits the effectiveness of Domri and Garruk.  If I were going to run two more I would probably cut a Domri and put Garruk in the SB. 

Destructive Revelry is AWESOME!  It's cheaper, runs at instant speed, and does 2 damage to the dome compared to Fade into Antiquity.  Obviously it doesn't hit the gods, and it isn't there for them.  It's mostly for Detention Sphere, Chained to the Rocks or other enchant removal, but is serviceable against all of the god's weapons.  It can also hit opposing Boon Satyrs, Unflinching Courage or any other troublesome enchant or artifact and do it at instant speed.   Every game I boarded the card in and drew it, it paid big dividends.  U/W Control D-Sphere's Polukranos, I take it back at the end of his turn and deal two damage, now my mana is free, Polukranos can attack and with the free mana I can monstrous him or cast a Stormbreath or double bloodrush with 2 rampagers or 1 rampager and Blood and he potentially has no response after tapping 3 for D-sphere. 

I've thought a lot about adding Fade into Antiquity into the sideboard.  Mono-Blue is a poor match-up if they get Thassa out early.  I have very limited interaction with their early flyers, main reason for Shock is downing a Cloudfin Raptor before it gets too big, or whacking Tidebinder Mage to free up one of my creatures.  If I don't get rid of those early then Thassa hits the board and starts making all the ground-bound guys unblockable I'm usually in serious trouble. 

Master of Waves isn't that big of a deal as Polukranos's Monstrous can hit it, though that is my only answer really.  His protect from red stops Flesh // Blood and Domri's fight ability from targeting him. 

I'll try to get to the rest of your comment a little later.

WRT Pithing Needle I'm just not that fond of the card.  When I do draw it, it seems to sit in my hand until the threat appears, then I play it.  Then it gets removed or they play a worse threat it also stops and I facepalm. 

The only thing I'd really need it for would be Aetherling and it's being played less now in the meta.  My beastly creatures are usually able to deal with a nuisance Planeswalker.  U/W/x control usually just minuses their Planeswalkers to get some value out of it before my creatures destroy it. 

Which just made me think of another "advantage" of Battledriver.  His 3 power let's him dodge Elspeth's second ability.

I would think something like Gruul War Chant would be a better option given that it provides a constant plus and makes your guys a bitch to block... and it's an enchantment, so it's not just a quick zap and it's gone.

That being said, what did you lose to?  Can you give us any thoughts on the games so that we might assess your match-ups a bit better?

Headed to fnm with gr monsters minus a donri and a stormbreath hoping to pickup stornbreath while im there the only thing i dont like is garruk... i run extra mizzium and an extra fleshblood and most the time i hit land and those spells lol i do however like chandra so was thinking of running 3domri 3 xenagos and 2 chandra main board any thoughts

I'm in the process of testing a new Jundish version of the deck: http://deckbox.org/sets/581107

I've noticed that in a lot of games with the original or some of the modified versions of G/R Monsters that because I only have limited life gain via Scavenging Ooze and limited removal to keep opponents' devotion in check I often lose because of Gray Merchant of Asphodel dinging me and gaining them life putting them out of range of my creatures and Flesh // Blood kills. 

This deck is already a good powerhouse of damage, but if it gets outpaced by devotion stuff it often falls behind.  Double Gary or double Fanatic of Mogis in consecutive turns often lead to disappointing defeats, where I've even had board advantage and was a turn or two away from winning. 

So inject Black, and lifelink, via Whip of Erebos which gives us lots of good stuff. 

Let me know what you think.

I'd agree that Scavenging Ooze often ends up under performing, especially if you're already winning.  But it's also straight up won me games when top decked mid or late game.  Particularly against control and Mono-Black Devotion matches where at least my graveyard tends to get filled up.  He comes in gains me back some life and becomes a 6/6 or 7/7 that can close a game especially with Flesh // Blood.

The Xenagos god is definitely a card I'm looking forward to testing in this G/R monsters shell.  I think 4 of is going to be too much though.  He's probably a 2 of.  He shares a mana slot near the top of the curve with Stormbreath Dragon and he's legendary so multiples of a card that is such a pain to remove seems bad. 

You usually don't want him in your opening hand that much compared to Domri Rade, Xenagos, the Reveler and Polukranos, World Eater. 

Drawing into him turn 3,4, or 5 would be ideal.  You definitely don't want to see more than one copy in your hand before turn 5 and if you run 4 of that might happen a lot.

Mono-black is going to cast Thoughtseize nearly anytime they get it anyway unless they've recently seen your hand and don't want to pay 2 life for any of your cards, then they might feed their Thoughtseize to Pack Rat or something.
