I'd been bored with this standard for a while, but stumbled on this Rakdos Powerstone list that top 8'd recently and its a lot of fun, while putting up results.

I too wish that RG modified was maybe half a tier better. The opening of oily G 1 drop, into +1/+1 counter on creature elf/ [[Kumamo V Kakazan]] followed by [[Feldon of the third path]] into [[Kodama of the West Tree]] is great provided oppo doesn't have any interaction.
Turn 1: Evolving Adaptive or Kumano Faces Kakazan
Turn 2: Quirion Beastcaller
Turn 3: Kodama of the West Tree for ramp, or Migloz for aggression
Turn 4: Halana and Alena or Thundering Raiju
If your opponent hasn't removed your stuff along the way, they're basically dead.
