Magic Deck – Alara Reborn Green/White?

I'm building a magic deck based off of one of the Alara Reborn starter decks. The emphasis of the deck is summoning high strength creatures and amplifying their strength further through enchantments. I've added cards that add more healing utility, to increase survivability and hopefully make up for some of the deck's shortcomings. My deck currently contains:

1 x Godtoucher
1 x Drumhunter
1 x Dauntless Escort
1 x Sunseed Nurturer
1 x Enlisted Wurm
1 x Mosstodon
1 x Qasali Pridemage
1 x Sigiled Behemoth
1 x Leonin Armorguard
1 x Knight of New Alara
1 x Vagrant Plowbeasts
1 x Pale Recluse
2 x Grizzled Leotau
2 x Wall of Reverence

2 x Sigil of the Nayan Gods
2 x Behemoth Sledge
3 x Cradle of Vitality
1 x Obelisk of Alara
2 x Indestructibility

1 x Captured Sunlight
1 x Reborn Hope
2 x Excommunicate

1 x Sigil Blessing
1 x Path to Exile
1 x Beacon of Immortality
3 x Soul's Grace

10 x Forest
12 x Plains
2 x Jungle Shrine

Any thoughts?
