Ambitious Dragonborn Animist's Might Bighorner Rancher Challenger Troll Choose Your Weapon Cream of the Crop Death's Presence Doom Weaver Emergent Woodwurm Exponential Growth - just cus Fanatic of Rhonas Mosswort Bridge Final Strike Fungal Sprouting that should give you options for the last few cards you have left. sadly you can't have Callous Sell-Sword in your deck because he has red in him, but all the other cards you added look good, especially One with the Kami and Necrosynthesis

Bouncer's Beatdown is a great kill spell for this deck because it's green, so people wont be particularly expecting it. The downside is you will have to have your commander out when you cast it or it'll be just about useless. All the soulbond creatures are a good way to do voltron while having blocks. I really like the idea of giving your commander undiying and then sacrificing him essentially for free. Indomitable Might Literally designed for this commander. Such a easy win con. You should add some sort of X spell such as Torment of Hailfire or Exsanguinate so you have somthing to do with all the mana you'll get from Tanuki Transplanter. I'll let you know if i have any other cards to add, but so far Fear Rogue's Passage Dryad's Favor are the only cards i can think of right now that give him unblockable. Hope you aren't planing to keep two copies of Garruk, primal hunter and O-Naginata in there (;

Garruk, Primal Hunter Return of the Wildspeaker Rishkar's Expertise Dina, Soul Steeper Dying Wish Essence Harvest Feed the Clan Fog of War Hardy Outlander Inscription of Abundance Predator's Rapport Rite of Consumption Tend the Pests Donno the pricess on those but I'm sure some of them will fit

Undercity Uprising Nightshade Peddler Altar of Dementia

and Vorrac Battlehorns Sword of Vengeance

You should add O-Naginata
