Mono-green devotion, fairly standard but will continually be worked around. Semi-budget and working around what I draft (playing a lot of it recently). This is meant to last post RTR rotations out, so I'm not putting in Burning-tree's or anything from Ravnica block or M14, as tempted as I might be.
Anyhow, very simple, I'm running 12x mana dorks so I can ramp up ASAP without dipping into red for things like
Generator Servant
this is mostly to keep Kalonian Twingrove strong and planted. I'm running a handful of 1x's to chord for, even with 2 in the deck it helps considerably with finding answers.
My biggest weakness (besides those inherent to the deck type like board wipes) is in the 3 drop slot, Yisan, the Wanderer Bard isn't particularly where I want to be in this deck, and at this point I really don't have a nice replacement in that slot, this is probably the area I'm keeping an eye on the most for Khans.
There's some obvious synergies in the deck, Hydra Broodmaster
+
Nykthos, Shrine to Nyx
+
Voyaging Satyr
can create a laughable amount of massive hydras that if unanswered are a very consistent killer.
Aspect of Hydra
is also here as a fantastic finisher, and can be side boarded out after the first match if used to keep the opponent on his toes and force him to block if I'm threatening lethal by only tapping 2 mana for a pair of them.
Bow of Nylea
+
Nylea, God of the Hunt
pair nicely, deathtouch/trample is insane, I'm not running a full set of either of them or Polukranos, World Eater because of the legendary rule, and the lack of card draw mean that sitting with a card in hand doing nothing hurts more than usual and I don't particularly like [life's legacy]] enough to play it.
Any advice/recommendations you've got I'd be glad to hear, this deck is by no means set in stone, just note that my wallet is not infinite though.
