White Green Populate and Lifegain if you play it right.
If people can slow you down, you get boned. Red and Black sniping with spells and murders and such suck, plus the deck is Enchantment heavy.Privileged Position x2 can mitigate that.
Call of the Conclave
is a really great way to start, usually save
Slime Molding
to combo with Parallel Lives and [Trostani, Selesnya's Voice]]. Martial Coup is an emergency board wipe that leaves you on top.
Growing Ranks
Stacks, and pairs with Parallel Lives quite nicely.
Mirari's Wake essentially doubles your mana pool, and stacks.
Luminarch Ascension is great for FFA or THG games, each OPPONENT counts, and if you can get Mirari's Wake out fast enough its a lot of Angels. Lots.
Rise of the Hobgoblins was put in as a last-stand emergency card, but it combos with Trostani, Selesnya's Voice and Parallel Lives really great.
Odric, Master Tactician because duh, attack phase control. Trostani, Selesnya's Voice works with anything that generates tokens (Rise of the Hobgoblins,
Growing Ranks
, Luminarch Ascension). Wayfaring Temple can get really heavy, nad it gets it's toughness before Trostani triggers, which can be great for your Health. Threw in Elesh Norn, Grand Cenobite for longer games, and Vorinclex, Voice of Hunger mostly to stack with the Mirari's Wakes.
Elspeth Tirel combos with this deck altogether. If you have a little token army, +2 counter on her and lots of life, -5 is for emergencies. Garruk, Primal Hunter can play really well, his +1 adds works great with Parallel Lives. -6 can be devastating.
Selesnya Charms keep the hard hitters out, and get you a Knight if you need to start populating. White Sun's Zenith if your high on mana, low on creatures, and it goes back into the library.
The sideboard is full of cards I've tried before and just kept them around in case. I throw in
Griffin Guide
to slow my cousin's Black Ramp Demon deck, and Sundering Growths because our friend has a super powerful artifact deck. To hell with that deck, Zach.
Hope I didn't babble on too much, I'm open to any and all suggestions!
