This deck makes use of efficient green creatures and spells to win the game quickly. The deck is very cheap even though it is very good.
Dryad Militant- A decent one drop with a relevant ability that is good against any deck that would hope to use the graveyard
Experiment One- If you can land this guy turn one expect at least a 4/4 because he will get big very fast. He also survives board wipes and removal with his regenerate ability. (Note: if he is 3/3 then Avatar of the Resolute enters with a counter boosting Experiment One to a 4/4)
Scavenging Ooze- He is great in the long games as the graveyards fill up and he becomes a monster. Great two drop that can quickly become bigger than your opponent can handle.
Avatar of the Resolute- This guy is amazing because he has trample on him, and I'm happy to play him on turn two with no counters but he stays relevant late game if you play by entering with counters. Remember he has reach because it is very easy to forget.
Strangleroot Geist- Fast beater who by the time your opponent might have an answer for, there is another bigger creature.
Kalonian Tusker- A simple 3/3 for 2. Not a lot to be said except this is an efficient card.
Leatherback Baloth- The stats on this guy are amazing and he bumps your devotion up three, great card.
Dungrove Elder- He's in here because he gets big if you get land flooded, but even if you don't he still has hexproof. Very difficult for your opponent to answer
Rancor- Even though this is an aura you can't be two for oned because it goes back to your hand to pump another creature. Try putting this on Dungrove Elder, your opponent will not be happy.
Aspect of Hydra- This card really makes this deck tick. I have cast this to give a creature +6/6 multiple times because getting a high devotion is very easy in this deck.
Vines of Vastwood- This card has so much utility. You can protect your creatures, pump your creatures, and even target one of your opponent's creature to stop one of there spells or abilities that targets it.
Treetop Village- A man land to help protect you from board wipes, and even though it enters tapped its usefulness outweighs the downside.
