Eldrazi Monument saves you from sweepers and you should have lots of extra guys to sac to the "drawback."

I like Skullmulcher for card draw, and you can't ignore Skullclamp either...despite its brokenness. Regal Force is pretty nice too for refilling your friends hand. Reliquary Tower would be a must have with some of these too.

Soul's Majesty is another one to consider for card draw. I use it myself in my Maelstrom Wanderer deck.

Ghave, Guru of Spores player here. have you thought of Sprout Swarm to pump out some saps as well as Doubling Season , Parallel Lives , and Primal Vigor to get more bang for your buck? you'd also want some ramp in there being a green deck Exploration , Azusa, Lost but Seeking , and Oracle of Mul Daya , all help get lands onto the field quickly. which leans into Avenger of Zendikar becoming a massive late game bomb. Caged Sun , Mirari's Wake , and Gauntlet of Power Buff your tokens and help you get more value for each land and makes Genesis Wave pull out all of your bombs at once on most occasions.

another few note worthy mentions go to Dungrove Elder and Kalonian Twingrove as solid creatures.

Selesnya Signet , Sol Ring and Ashnod's Altar as some Budget(ish) Artifact ramp.

I forgot to mention Rhys the Redeemed as a solid Token Generator and secondary commander.

If $ isn't an issue the deck wont be hard to put together. mostly I noted your missing Rhys the Redeemed & Doubling Season. and I always suggest Mercy Killing personally.

-Selesnya Charm-Aura Mutation-Emmara Tandris-Pollenbright Wings-Selesnya Evangel-Selesnya Guildmage-Tolsimir Wolfblood-Vitu-Ghazi Guildmage-Voice of Resurgence-Wayfaring Temple

A few of which may be out of your "price range" but there my personal fav's for token decks...

Check out my deck Revenge Of The Conclave it will give you tons of ideas for cards. Hope you finish it on time +1

Thanks for the comments and suggestions. Budget isn't much of an issue. What I can't buy I can trade for. That said I would like to stay away from costs like ABUR duals. We may have been friends for 19 years, but I don't want to spend that much on him.
