Rites of Flourishing, Explore - Extra Draw and Land
Courser of Kruphix - Play lands from your library and gain a lot of life, especially if you're able to play additional lands.
Oracle of Mul Daya, Azusa - Wow, more additional lands.
Lotus Cobra - Super Mana Ramp, especially when you can play additional fetch lands.
Seer's Sundial - Draw Engine (This is very useful when you have Lotus Cobra in play too).
Elixir of Immortality - Running out of cards? Need more fetch lands? Maybe you need more life? This is the answer to all problems.
Rampaging Baloths - This guy is the wincon, try not to lose count of all your beasts.
Fetch Lands - Good for activating landfall twice.

Sideboard:
Worldspine Wurm - Second wincon if necessary. Good against removals.

I still need help with the sideboard, please give any suggestions :)
