Selesnya (Budget,Casual, Noob)

This is my Selesnya Budget/Casual/Beginner deck for playing w/friends.

Main objective is basically populate, populate, populate, populate, populate, populate and populate.

I already own Garruk Relentless because my friend gave to me since I have more of a favor towards green in our group, and since he is going full out Rakdos Aggro (which as he went far enough to pay our "magic veteran" friend to make him a deck for him and bought the Rakdos Guildbox from the Pre-Release off of Amazon.

My sideboard is kinda of my board to switch ahead of time depending on what deck my friend will play, since usually we only have 30 mins to play Magic during school which is Focus ( a school wide class for 3rd period where we all students are required to do "work" but depending on what focus teacher you have and how laid back they are, it can be just a social period basically. )

What I would do, is to maybe takeout some Vitu-Ghazi Guildmages out, but then again I need populate ASAP, so having 4 would give me a higher chance of pulling her out and using the populate as spell as much as I can quicker. I saw how some people used mana-dorks like Elvish Mystic and Avacyn's Pilgrim because of that, which I thought was cool so I added some in.

And those Heroes' Reunions are just there because I just happend to have four of them, might help against my friends really good Rakdos Aggro deck.

Any advice to tweak this to the best it can be and what to do to make this 60 cards would be appreciated.

P.S. the reason why this is budget because I'm not sure how well into Magic I will be in the next few weeks, if I get really into it I will consider putting really nice Selesnya cards
