Well, the big question you need to ask yourself is how often do you miss the second plains for Silverblade Paladin.  Because that is the only 2 white card you have in your whole deck.  If you feel like you keep missing the 2nd white source, then I would keep them in.  However, if you draw Arbor Elf and Temple Garden, that acts as your second white source due to it being able to untap forests.  This allows turn 2 Silverblades, which is something you cant do with Farseeks.

This is a fairly standard Selesnya Midrange actually.  My one issue is that I dont think you need Farseeks.  I generally prefer to just run Arbor Elf, as it effectively gives you one more mana for one less, and it is also a little bit of board presence.  But beyond that this would do quite well at FNM.
