Made a few changes.  I'm not seeing how I can add in the things you guys have mentioned and cull down to 60 cards without compromising the spirit of the deck.

Here's my thoughts:

Gatecreeper is my card searcher and also additional defender cards to fuel Axebane Guardians
Axebane Guardians tap for any color mana equal to numer of defenders controlled
Avacyn pilgrims and arbor elves give some mana boost
Ground seal takes graveyards out of play
Sundering growth removes enchantments
Growing ranks and parallel lives are the core of my populate engine
Tokens come from Garruk, call of the conclave, grove of the guardian, and selesnya charm
Life gain from Trostani
Root born defenses and Druids deliverance nullify conventional attacks to allow time for token generation and population
If all works well Wayfaring temples will be my big creatures and further fuel my populate engine

So far things seem to be working fairly well.  What are the weak points and how can they be shored up without subbing in a lot of pricey cards?  What should I be sideboarding?
