I recently joined the magic community and only play magic online. I've played Planeswalkers-2014/watched youtube. So I have a general idea of mechanics of some different decks. Basically I would like suggestions on what I could add or remove to improve the win rate and funability, if possible.

What I was going for was a Standard-mono green ramp. I also like the idea of Green/white, Selesnya- (using that mtg lingo).

Any help is appreciated, thanks.
