Also, any suggestions on things to take out for Heroes' Bane or Hydra Broodmaster ? I'm probably going to take out Naturalize , but I don't know what else...

So your general only triggers when you 'cast' creatures. Just out of curiosity then, why all the token production? I think it would be better off in decks like Rhys the Redeemed . Here I would look at cantrip style creatures like Elvish Visionary and Multani's Acolyte . Once you have your general they draw you a card and grab you a land for 2 mana. Before she is out they get you the land you need to cast her.

Usually the only tokens I wind up spawning are wolves and saprolings, wolves buff the creature that has Raised by Wolves and I'll probably replace Sporemound when I finally get the hydras from journey into nyx. Sigil of the Empty Throne is in there because I have almost no flying and one of my friends has an angel deck, I never seem to draw it though.

Check out Gravity Well and Spidersilk Armor , they might help the flying issue.

I've been playing a Karametra, God of Harvests deck with a large amount of success, if you'd like to look at it for ideas Karametra STOMPY TIME!. A few cards I've gotten a lot of mileage out of are Lotus Cobra Amulet of Vigor Wolfbriar Elemental Rampaging Baloths Kamahl, Fist of Krosa . I hope This helps, +1ed for being a solid deck too!

Cloudstone Curio will let you put things back in your hand to re-ramp and etb with.

Not including Whitemane Lion is a crime in a karametra deck. It can choose itself in response to it's own etb ability, you can cast it for as much as you have mana. Kor Skyfisher , Dust Elemental , Stonecloaker , and Emancipation Angel all are in the same boat. Add in Stone-Seeder Hierophant and Selesnya Sanctuary for an engine that triggers all of the landfall that your deck should have.

Mistcutter Hydra (x = 22) + Ghoultree + Noble Quarry beats my new Pharika, God of Affliction deck. but pharika held out long enough for a 22/22 mistcutter hydra. 5 creatures dropped after karametra hit the field.

is 29 lands enough?? apart from that i can't offer any suggestionsmaybe a if so why not run more dual lands

after turn 5, lands are dead draws because I can put them out with any of my creatures. true they come in tapped, but still, I never seem to have mana problems.

Stone-Seeder Hierophant and Nykthos, Shrine to Nyx would rock.

i'm probably just going to comment on every Karametra deck that doesn't have Stonecloaker in it that it needs Stonecloaker . this dude has so many abilities. while instant-speed graveyard hate + save/replay another guy or bounce itself for more graveyard hate is good on its own, it's nuts with Karametra out, because you get to rampant growth repeatedly by bouncing itself.
