Green/White Aggro Decklist

For the last two FNMs I have been fidling around with a Green/White Aggro deck. The reason I built this deck is that I got a Sigarda, Host of Herons and wanted to build a deck with her right away. The first week I played the deck I went 4-1 with my only loss being against a B/U Zombies list. The second week I played this deck I went 5-0, I had to play my dad in the finals (which kinda sucked) who let me win thinking he had better tie breakers. Well enough talking about the deck so Here it is after two weeks of playtesting.

 

Creatures: (25)
Avacyn’s Pilgrim
Birds of Paradise
Strangleroot Geist
Silverblade Paladin
Wolfir Avenger
Hero of Bladehold

Non-Creature Spells (14)

I want to take out the Faith`s Shields and Increasing Savagerys for more creatures. If anyone has any suggestions on my deck I`m open to other player`s thoughts
