Guff is an obvious choice to help ramp early and provides draw.
Rhythm is a good choice to distract opponent while we dig and ramp (mostly go for first choice)
Others are good for ramp and armour.
i always keep twig but probably not the best.
E.T.C = Jade Idol, Astalor, Photographer Fizzle,
Jade Idol is for any deck with infinite card draw such as Jade Druid.
Astalor is just for an alternate win if you need to use cards before combo to stay alive.
Just came up with this and went 5-0 (Still Testing)
Combo Is Anub into lincracker combo and then zok. You can do this with twig or Floop both get enough mana.
I added harmonic mood just to give tokens attack but actually found a couple times in my games to keep the attack 1.
