Firstly I'm assuming that this isn't a standard deck, rather modern or something. I think that Yeva, Nature's Herald doesn't belong here. I'd replace her for some more early ramp like Llanowar Elves , Arbor Elf , Rampant Growth , Noble Hierarch or Farseek if you're planning on adding another colour.

Kalonian Hydra is one of my favourite cards, but too bad I can't afford them :(

Also for some reason when I went to play test this deck, there was only 1 forest in the deck. Wierd :\

hey thankyou for the comment i will take out the Yeva, Nature's Herald for Farseek and yes i love my hydra Kalonian Hydra and Primordial Hydra are great and is a good combo which is what im trying to make this deck do (which is multiply counters) i havnt been playing magic for long either so i appreciate all help :)

i have also changed it from what i want it to be to what it is right now once i get 3x Primordial Hydra i will take out Voracious Wurm

I'd only say add Farseek if you're adding another colour. Because the only land you can't get with Farseek are forests, which doesn't really help in a mono green deck.

ahh i see, so the question is to myself and you though is i dnt no what colour will be good added to it i was only thing white/blue because of the lacking of killing or counter with spells or red with a Savageborn Hydra but other then that i rckon i should stick with mono green and buy some Noble Hierarch

sorry about my english i suck at sentences

Another option would be to keep it mono green and get some Gyre Sage . With evolve it'll get +1/+1 counters which works well with Kalonian Hydra . Also I'd chuck Naturalize into a sibeboard rather than mainboard.

But it's really up to you which direction your deck takes.

i shall do that that would work great with my plan

Well i ordered my 1 Kalonian Hydra 3 Primordial Hydra 4 Gyre Sage so my deck sgould be nearly done once they arrrive

Why is Voracious Wurm in here, since it seems like you have no life gain? Slitherhead might work well in this deck, considering its a zero scavenge and putting the extra counters on the hydras would be awesome. If you could scavenge that on Primordial Hydra its double would be greater next turn. just a thought :)

i know what you mean but i will be taking out voracious wurm for 3 Primordial Hydra and i will be taking out Yeva, Nature's Herald for Gyre Sage , and about Slitherhead , with Kalonian Hydra 's ability and Primordial Hydra 's ability itll be doubling all the time, but thnx for the comment

I found this deck recently that I really like. It's Hoof, There It Is! by TheHazzaRd. You might want to check it out and play test it as well.

Thanks for the shout out guys! Good to see my decks are out there. In this particular 75 (or 77) I'd be replacing Vastwood hydra with Primordial Hydra - doubling your counters each turn vs moving them when you die is a no brainer. Assuming your mana base and wallet can hold out, I'd move this to Jund (B+G+R). It gives you access to sweet sweet removal - Dreadbore , Abrupt Decay and Putrefy - and a handful of cards that interact really well with Hydras, Corpsejack Menace and Savageborn Hydra . Good luck!

thanks TheHazzaRd i have a rakdos deck so i have the Dreadbore 's but nothing of the others but other then that i wouldnt no what to take out but i have been looking for way to have some removal

okay so you'd need to go from the ground up and rebuild this as a Jund Hydra deck.we need to pick our absolute core cards.Kalonian Hydra , Primordial Hydra and Savageborn Hydra give us our tribal backbone.Corpsejack Menace turns our T5 play into an absolute threat.Elvish Mystic gets us there faster, as does Farseek .Deadly Recluse keeps us alive and gets rid of flyers.Rancor is the best aura ever printed.so from there we want to play the better fill in cardsDreadbore Abrupt Decay and Putrefy are the best removal.Ulvenwald Tracker is great with recluse, and good removal anyway.with all these +1/+1 counters, Exava, Rakdos Blood Witch could be a lot of fun.Yeva, Nature's Herald can still make an appearance.so at the end of the day we come up with something like this

Jund Hydras

I would use Dreadbore instead of abrupt decay cause i.allreaddy have 4 of them unless i order all.the ones i.dont have

Voracious Wurm seems really bad in the deck since the Staff of the Wild Magus is your only life gain and its in your sideboard. Maybe Scavenging Ooze would work better. +1

I just pisted an update but Voracious Wurm was only a filler till i get ehat i needed but i only have 2 scavenging oozes

oh sorry I forgot how Kalonian hydra puts counters on other creatures as well. I saw the comment about farseek, so instead why not use Lay of the Land ?

A question about this mono green hydra deck how would Bioshift

can you switch counters over if someone blocks and kills your creature and then you switch the counters to another creature before it dies? I'm not sure of this.

Yea its an instant

then that would be a pretty effective combo

Great thnx
