I might remove Swordwise Centaur , and possibly add instead Reverent Hunter . Also, mainboarding 2x-4x Garruk, Caller of Beasts might be a good idea, he's too good to pass up, particularly in a deck consisting of just dudes. Also, definitely add 4x Nykthos, Shrine to Nyx , remove 4x Forest , as with a good amount of devotion and ramp and only 20 land, it might be a good idea to add a way of being able to just dump mana into something like Mistcutter Hydra .

Cool deck tho!

Im going to get Garruk, Caller of Beasts pretty soon :D. What you said about pumping up Mistcutter Hydra is something i have been thinking about lately. The synergy there would be really good with the Nykthos, Shrine to Nyx . Ive not really thought about Reverent Hunter .... Now that i think about it though...many games i play against my friends end up with me getting many creatures on the board, so it would be really really good.

Thank you for the suggestions!

With all the mana production you might want to add in some more hydras such as Kalonian Hydra and Nylea's Disciple for some devotion based life gain.

You are going to be destroyed by flying creature decks as you have no answer to flying.

You might want some protection there as well in the form of Ranger's Guile protect yourself with some Fog in early game.

Its a good start to a deck but it does need some thought into other decks that you will be playing against.

If you like the value of Kalonian Tusker maybe try Burning-Tree Emissary

I agree that Garruk, Caller of Beasts is a must, probably as a 4-of. Also, you probably want about 22 lands, and should have 2-4 Nykthos, Shrine to Nyx among them. If you do add Nykthos, you'll definitely want Burning-Tree Emissary . Hunter's Prowess is a good way to get one more form trample and card advantage. Finally, Boon Satyr is a great option in these decks.

I would remove all of the Centaurs, Vulpine Goliath, and a couple Karametra's Acolytes

@MadScientist

I really like the idea of the devotion life gain. Ill definitely consider adding it. Kalonian Hydra is definitely a really good card. Ive been trying to get some for the past few weeks to add to my deck. On the subject of devotion life gain i just thought of a really good combo. So imagine i play Nylea's Disciple , and the play something like Voracious Wurm . i could easily have a 8/8, or bigger, for 6 mana, and i would have gained a lot of life.

I realized my weakness in the air, which is why i made an anti air sideboard. Im not really sure what to add to the main deck which can handle flying without being a sideboarded card. If you have any off the top of your head i would really like some help with this.

I have actually been hunting down a couple of Fog lately. Ive been wanting to try it in my deck.

Thanks for your suggestions!!

@Rman92011

Hmm ive not actually heard of that card. It looks really good!

Thanks for your suggestion!

For flying removal there are some simple creature cards that can be really helpfull

Nessian Asp - has reach to catch flying and can go monstrous, with your mana generation that could be seriously powerful.

Deadly Recluse - low cmc deathtouch/reach this little guy can be so annoying as it will stall a board with a giant flyer on it as the opponent does not want to lose there 5/5 to little weenie.

If you could work them into the mainboard you would have flying protection.

@ChrisHansonBiomancin

I agree that Garruk is a really important card for my deck. I have been trying to get my hands on him for some time now.

Why do you think i should have 22 lands? I agree with adding Nykthos, Shrine to Nyx . I have also been trying to get my hands on a couple of these as well. Burning-Tree Emissary seems pretty good.

When i first started construction of this deck i have wanted Hunter's Prowess . I am getting them really soon :D

I used to think that Bestow creatures were bad, but the way this deck has evolved, it has made me think differently about having cards like Boon Satyr .

The only reason i have Vulpine Goliath was because it was a big drop that could dish out some damage, i was eventually going to take it out. Ill have to give some thought about removing some Karametra's Acolyte . Since i dont have any Nykthos's i kind of depend on it for my massive amounts of mana. When i do get some Nykthos's i will probably remove some of them, but for right now im going to keep them in.

Thanks for your suggestions!!

@MadScientist

Thank you very much! Ill start thinking of how to work those in.

First of all, let me congratulate you on building mono-green for your first deck. Mono-green is my favorite color by far. However I think there are a few ways to improve your deck. You can make it faster and much more lethal. Oh and as you read this you may start to realize it'll be shifting away from a midrange deck, but please read through anyways as that will be explained at the end. Ok, here we go.

First of all you need a really big creature to beat down your opponent. Start off by removing 4x Swordwise Centaur and replacing it with 4x Colossus of Akros . While it can be nice to have a 2-drop to play early on you already have 4x Kalonian Tusker which are actually stronger. Having too many 2-drops, in a mono-green deck especially, can be devastating late game. You'll end up pulling one or two of them when you need to be pulling something big to stomp your opponent. Not to mention Colossus of Akros is about the biggest thing you can run in standard green. Now I personally would also remove the 4x Pheres-Band Tromper in order to add 4x Giant Growth . The reason for this is because Pheres-Band Tromper is too slow but on a trampler an extra 3/3 can be a finishing blow. I would also drop 1x Polukranos, World Eater and the 1x Vulpine Goliath In order to add 2 more Arbor Colossus (he's a 6/6 with reach for 5 mana. That's a great deal, plus he adds 3 devotion to green for your Karametra's Acolyte and Nylea, God of the Hunt ). Last but not least, remove 2x Mistcutter Hydra in exchange for Garruk's Horde . When you've got lots of mana to blow Garruk's Horde 's ability will be more useful than just dropping a really big hydra. Now all of that might have been a little confusing so here's the end result which you have inspired me to create. Green Devotion Standard

P.S. I know this is supposed to be a midrange deck (which it still kinda is aside from the big ol' Colossus of Akros and Garruk's Horde ) but hear me out on why my changes are actually really good. In order to make a decent green deck you're gonna have to use Karametra's Acolyte right? Right, well by still using your midrange cards like Arbor Colossus , Kalonian Tusker and Polukranos, World Eater a single Karametra's Acolyte will be tapping on it's own for at least 6. Combined with the 4 mana you had to use to cast it in the first place, you've got 10 mana sitting around. It just makes sense to play something bigger that a 5 or 6 drop card at that point.

@Dr.Woodenstein

Thank you very much for taking the time to help me on my deck! :D Having this deck be midrange was never really something that had to happen for this deck. i just wanted to have hard hitting creatures for both early and late game, which if i add your suggestions will be really improved in my opinion.

Your suggestions make a lot of sense to me, and it gives me a lot to consider. I agree with you that having access to a lot of mana is kinda pointless if all im playing is small creatures,etc, so ill definitely be taking some small creatures(plus the Pheres-Band Tromper ) out and putting in bigger creatures. The cards you have suggested never really crossed my mind, but they do seem really really good. I think i know what direction this deck is going to go into now.

Can you give me a little insight as to why i should add two more land? I feel i could add something more useful than just land, especially when you take into account all of the mana ramp i have.

Thank you so much for your suggestions!!

Thanks, I'm really glad you like my suggestions. I absolutely adore mono-green so I try to keep up on all the best green cards available.

Before I explain the land situation, let me throw around a few other standard legal green creatures you might want to look into. Worldspine Wurm is super awesome and about as big as you can get with green, Giant Adephage is just about guaranteed to multiply after being hit by a Aspect of Hydra (and yes the tokens that Giant Adephage creates will also create copies of themselves when they deal damage), finally Skarrg Goliath can bloodrush a creature for a killing blow or just come into play as a huge creature (he's super cheap too by the way). If you want help fitting any of those in just let me know.

Ok, now as to why you use 22 lands. 22 lands is just the best ratio in an average deck to make sure you have enough lands when you need them to play what you want to play. Also if you notice, the deck I made was 62 cards, that was on purpose. The rules of Magic state that your deck has to be a minimum or 60 cards and can be as big as you want as long as you can shuffle it in full unaided. Now when you make mana-ramp decks sometimes you decrease the number of lands to 20. That doesn't mean you increase the deck size to 62 using other cards, you're decreasing the number of lands in order to increase the chance of drawing other cards. However, I feel that the ramp in standard at the moment is a little weak, so I'm going for the full 22 lands (that may change though). One thing to consider, is trying to play a set of Gyre Sage cards to increase your ramp. Gyre Sage also has the benefit of being able to be an attacker and a blocker late game, but it will not tap for any mana until it evolves the first time. Hopefully that was helpful to you.

Just wanted to say I really enjoy the changes to your deck, I'm gonna think about your sideboard and get back to you. One important note for sideboards though is that you have to consider the meta in your area to really know what to put there. So if you could give some idea of what really troubles you when you play against your friends or at FNM or whatever it would help.

By the way, I don't know if you noticed or not but we both just commented on another guys green deck. I thought that was kinda hilarious, just saying.

Thank you for all of your help Dr.Woodenstein!!! I really appreciate it.

I have started to realize that about sideboards, so I'll see what I can come up with.

Yea haha. I did notice that! I found it funny as well.

Look up the card "Setessan Tactics," that's coming out in Journey into Nyx. I think you'll find it right at home with this deck, or at the very least, the sideboard. +1

Thank you very much ddubbs88!!

I really like the card, and agree with you that it would fit nicely into my deck or sideboard. Ill definetly try to fit it in somehow, because with my ramp, it would basically be a board wipe if i had enough creatures on the board.

Another great "board wipe" with the amount of devotion in your deck is Wild Beastmaster after being hit by Aspect of Hydra . Another great card for this kind of deck is Reverent Hunter , a little random I know but I don't think I've mentioned it before. It does need trample added to it and that may not be practical.

What should I remove to put in two of Garruk, Caller of Beasts

Well there's a couple of different options there. Deadly Recluse is a choice. Garruk's Horde is another possibility. If you're finding the number of instants you have unnecessary you could drop a few of those. I would also suggest considering dropping Polukranos, World Eater . It's really just going to depend on what you think is the least needed at this point. I do want to mention that Garruk, Caller of Beasts may be ineffective in this kind of deck.

Thank you for the suggestions! Why would Garruk be ineffective?

Well as far as I'm concerned at this point, if I want him in my deck it's for his -3 ability. I can play something like Worldspine Wurm (an 11 drop) for 6 mana through Garruk. Unfortunately that's only for green creatures and your only green creature that costs more than 6 is Garruk's Horde . I highly doubt you'll kick off his main ability in this deck, it'll just take to long and you'll lose too many creatures trying to protect him. As for his +1 ability, it's nice but it's going to make you put your instants, enchantments, and lands on the bottom of your deck. He CAN be useful if played properly, don't get me wrong, but I don't know that he would really add much. You'd be much better off building him into a non-standard deck. Unless you add something stupid big like Worldspine Wurm .

Hmm. that helps me alot. Thank you very much.

I have a mono green deck, too: Legit Mono-Green Burn (Is That Even Possible?). You should check it out.
