I'm totally not sensing your love for your edh.

For starters, I think you're running way too much heavy casting stuff, even with card:Gaea's Cradle. I suggest removing card:Death's Presence, Garruk Relentless  ^Flip , Vigor s and reducing your Howl of the Night Pack . card:Wren's Run Packmaster is a good card that'll keep your wolves flavorful. Sylvan Scrying will help you fetch your cradle, but even then, I'd use Crop Rotation .

Now, if you're willing to splash white, you can use Watchwolf , Tolsimir Wolfblood , and Juniper Order Ranger . The ranger is completely stupid and powerful. Furthermore, you'd have access to white control spells like Path to Exile , Oblivion Ring and more. As for card drawing, Glimpse of Nature is preposterously good, if you aim for more cast creatures and less token creatures.

Oh, also, you may want to consider more card:Gaea's Anthem, Beastmaster Ascension , and Coat of Arms to boost everything. Moonmist is a good finisher too.

I agree with Alizer313 with a lot of their suggestions (and I see some were taken into consideration!)

My only input would be think about Champion of Lambholt to just have them walk on through without consequence after you pop out a few creatures.

This looks like a nice deck, but you should consider turning this deck into modern format. you would have to only take four cards out of the deck and add some mana givers, and i think you should take out the Carnage Altar 's because they are too expensive and slow to use. Also you should consider Garruk Relentless  ^Flip but hey, that's just my opinion.

Thanks for the idea! What cards would I need to remove exactly to make it Modern? And do you have any ideas of what would replace Carnage Altar ? (Other than Garruk Relentless  ^Flip ?)

Since you have very little creatures, perhaps Llanowar Elves would be better to have than Somberwald Sage

If you didn't know, Modern format features all the cards from 8th edition to the newest set(expect for the banned cards of course) This deck needs more 1 mana drops so it becomes little bit more competitive. (: There are so many legal cards in modern so you should take so time and search MTG forums, google and other green decks.
