imo i would not drop the Ash Zealot i really think its a great card for what it does and i second shake with the drop vexing devil part. id swap that out with ethier Experiment One or Stromkirk Noble as far as the loalyist i have not been crazy impressed with it. Def save up for hellrider for the deck and if you can somehow get ahold of reckoner do it but they are so over priced unless you trade for it dont bother wait till it drops. keep in mind flinthoof boar is a great card to use but if you dont get that mountain then its just a Grizzly Bears so dont over look geist and zealot
I was also thinking about maybe Arbor Elf as some extra ramp and even though the Hellraiser Goblin causes you to have to attack every turn with everything that can, if i play this right though, it should be over by turn 3 or 4 and I will not have taken enough damage to kill me.
play 1 mountain tap 1 forest, tap 1 arbor elf, untap 1 forest, "float" one , tap 1 forest, play 1 strangleroot geist, swing for 2
turn three draw 1 burning-tree emissary
tap 1 forest and 1 mountain and 1 arbor elf, untap 1 forest play 1 burning-tree emissary,play 1 burning-tree emissary, play 1 burning-tree emissary, play 1 burning-tree emissary, play 1 hellraiser goblin, swing for 10
turn 4 draw 1 flinthoof boar
tap 1 forest and 1 mountain, play flinthoof boar, swing for 14 done. for a total of 26 damage, all from 2 lands...
So I removed the Ash Zealot and the Vexing Devil opting for the more mana-base friendly Strangleroot Geist I added the Slaughterhorn mostly as a combat trick, for one target creature gets +3/+2 I'm in, the Rampager is also there for the same reason. Ive also added a little burn and changed up my mana base to reflect the more "pro-green" line up.
