Ok. SO your deck is "apparently" not "meta" enough for ladder or competitive. No offence. Yes, we love a picture of Vaath smiling, but your deck needs a bit of work. SO here's my daily dose of reality for you(K-2S0 style), there is not enough removal, too much healing, and not enough spells. Sorry.

I'll explain my card choices, this may take a while.
Amplification: Chances are, your grow minions will get damaged during your opponent's vain attempts to destroy them, so why not make it harder and give 'em a health boost with some extra ATK.
Godhammer: 1 is not enough. 3 is too much. Fun Fact #1: Godhammer, when more than one is equipped, you minions get grow:+1/+1 multiplied by the amount equipped. Fun Fact #2: People will try hard to insta-kill the minions you summon while you have godhammer equipped, so there is a guarantee of their general taking some extra damage.
Greater Fortitude: So your grow minions don't die instantly.
Cascading Rebirth: Fun Fact: Use it on a 5-drop(dispelled Kolossus), and it'll guarantee you a Mankator Warbeast, because it's the only six-drop in Magmar. Otherwise, use it on any dispelled-expensive minions.
Diretide Frenzy: "Oh look, a 25 ATK Kolossus nearby my general! Good thing I have a provoke minion nearby..." uses Diretide Fenzy "NOOOOOOOOO". You get where I'm coming from, right?
Entropic Gaze: Card Draw.
Natural selection: Chances are, you'll have a bunch of high ATK, so why not some easy 2-drop removal, hmm?
Earth Sphere: "I'm lethal! I'm lethal!" earth sphere "..."
Egg Morph: Much more specialized removal.
Thumping Wave: Removal, or a go in for the lethal.
Plasma Storm: "AAAAYYYY, Sirroco!" Plasma Storm "CAN U STOP RUINING MY EPIC MOMENTS!?"
Gro: Because gro.
Phalanxar: It's Phalanxar, insta 6 damage. gg
Rancour: First one will die, always. So keep a backup. You can substitute a primordial gazer for twin fang for maximum damage.
Earth Walker: Why not? Something you can use on turn one.
(Note: Swap out Earth Walker (x2) and Threax for 3x Sunsteel Defender. Because Sunsteel Defender OP)
Moloki Huntress: If it isn't obvious enough it's a GROW DECK. FOR CRYING OUT LOUD
Primoridal Gazer: Greater fortitude substitute as well as a 2/2 body to hit something.
Threax: (Note: swap out whatever you want for a cryptographer for maximum effect) who don't want a +1 ATK on everything for a BBS?
Grimrock: They'll hate us now...
Kolossus: Ok, they loath us...
Veteran Slithar:8+ damage if left alone.
ENjoy, and leave any ideas for improvement below.
