Thank you so much. Any idea what I should do for dual lands and what ratio the green/blue/white mana should be?

If you don't mind spending a bit you could add  {Thran Quarry}

Guildgates or the new Scrylands? Oh, and the {Obelisk of Bant} is always a good start.You could also try {Simic Growth Chamber}, {Azorius Chancery}, and {Selesnya Sanctuary}.
