Ditch the sacrifice parts and go all-out on creature generation?  (So, drop the Falkenrath Nobles, for instance.)

Cards to maybe take out:
- Bloodflow Connoisseur (doubtful)
- Falkenrath Noble (likely, it's horrendously effective but slows games down too much)
- Kozilek's Predator (love the card, and it's handy as, but I may be better off with mana-fixing or a direct source of +1/+1s)

Cards to maybe put in:
- Intangible Virtue
- More Mycoloths (for the obvious reason)
- Increasing Savagery or some other 'give me +1/+1s' card
- Korozda Guildmage
- Axebane Guardians and/or more Gatecreeper Vines
- I could take out the Falkenrath Nobles and put Unruly Mobs back in to replace them (they're cheaper, and arguably synergise better; they certainly fit the theme better)
- From teh interwebz: Mikaeus, the Lunarch! :o (In fact, other-Mikaeus would be great as well.)

Rings?
