I've gotten it twice now. The slab along with the god pack I've broke about even. Which is better than a lot of mystery boxes, outside pulling a heavy hitter. Love the little god packs. Definitely a chance to pull some cool cards. In my opinion, one of the better mystery boxes out there.
You get about 100 worth at most in total including the "extra pack" mostly bulk. The more you spend the better you'll get but think 80% of what you've spend bought twice nothing good a grade EX, I will say they are a 10 only good thing
