The deck is a scion Factory!! You should have Tons of the little critters! With a good hand you can have Sire of Stagnation out third turn, basically shutting your opponent down from Land deprivation.
look to kill of Blisterpod the scion is twice as useful! A good way to do so is with Evolutionary Leap this will also thin your deck out and grab you another creature, if you have Cryptolith Rite out this action becomes free, simply tap Blisterpod using Cryptolith Rite and then use the mana to sacrifice Blisterpod to Evolutionary Leap
There is an "infinite combo' in the deck; Cryptolith Rite + Paradox Engine + Temur Sabertooth it's not all that hard to get off but isn't necessary to win with this deck. the sequencing should go like this; Tap any three or more creatures to Cryptolith Rite and bounce a creature using Temur Sabertooth then recast the creature Paradox Engine will untap the creatures used to generate mana, repeat this process. This will generate INFINITE mana and trigger any etb affects INFINITE times.
What to do with Infinite mana?? Bounce
Eyeless Watcher
or
Catacomb Sifter
for infinite scions, Bounce Kozilek, the Great Distortion to draw a new hand when your out of cards (dont mill yourself out) or Ulamog, the Ceaseless Hunger to exile ALL of your opponents permanents!! Or my personal favourite; bounce Genesis Hydra to Tutor all non-land cards from the deck!!
Nissa, Worldwaker not only turns your forrests into 4/4 creatures but with a Cryptolith Rite 4/4 forrest creatures can tap for ANY COLOR of mana.
Warden of the First Tree
is just great value and can always be cast first turn as all lands produce green mana, he also becomes a great outlet to pump unneeded mana later on as his final ability is repeatable.
Feel free to experiment the List isnt set in stone! be sure to notify me of any changes you make it helps alot!!
