I had a fantastic pair of prerelease kits as far as value goes, I played one round (lost) and then dropped. Sold a few things out of my prerelease kit and covered the difference to buy a box. This is the result:
There was only 6 people at the tournament. My rares/mythics were Ugin, Fabled Passage, Kaervek, Runed Halo, Speaker of Heavens, Shacklegeist and Solemn Simulacrum (promo). I played WR and went 2-0-1. I won 4 packs. My prize packs had another Fabled Passage and an borderless Chandra.
