New (prism) player looking for booster box advice

I'm relatively new to FAB and I have played a bit of blitz with some friends. My question is what booster box would be the best option for someone who wants to make a prism, awakener of sol deck. After looking around a bit I think I'm looking for the monarch booster box, but I figured I would ask first before buying a box. I know that buying loose cards or a completed Deck would (probably) be better and cheaper, I just want to have some fun cracking packs :) Thanks in advance for any advice!
