I am new to modern magic. I have been playing limited the last couple years. I wanted to get into construction and I have always loved Elves. I played in my first FNM last week and went 3-0 against Tron, Jund and Burn. Here is my current list and my other sideboard that I have considered. What do you guys think? I know I probably need Cavern of Souls but I can't pick some up yet. I think the field this Friday will be around 25.
