This reminds me of the Wizards of the Coast article: http://www.wizards.com/Magic/Magazine/Article.aspx?x=mtg/daily/rc/214
Maybe you could take some suggestions from there.
Replace Fog with card:Druid's Deliverance. For sure.
I agree with KanvasKing, card:Druid's Deliverance is better suited to your deck. I would also say to try and add Parallel Lives . It can work really well with this deck, and it would swarm your opponent with tokens. I really like this deck and the combination of Green, White, and Blue. :)
Try cackling counterparts. Creates a token, so you could use it on Thragtusk and populate for game.
the deck is standard , man =thnks all for suggestions and +1
i would take out 1 closte the only spider and 1 life doubler for 3 Centaur Healer 's
closet is essential, but I liked the centaur, I'll take the spider and the side thnks
If you find your games regularly going long you should try a Serra Avatar in there somewhere, it gets a bit bonkers when it drops :D
I like this deck... im gonna modify my bant deck and make it a little more like this one.
