Pulling the mystery shards will definitely take a minute 😂 I was like 600 points away from something awhile ago, inly had about 2000 mystery shards so I decided to try and pull em until ai got 600 points. After 2 hours of feeding champs and using silver, i said screw this. Lol. Think I got to like 250 points?

I would say if you have the patience to do it, then yeah, use your mystery shards and get that book. It'll definitely take you a while, though. I would say definitely *don't* use the ancients and voids.

I will do a quick test on 100 and see if I have enough time left.  

Bit late to the party but I'm with kram on this one. Plus, 1200 mysteries isn't too terrible. :)

822 mystery shards in less than hour and a half.  I got 22 rare out of it.  The dupes will go into guardian.  Where I have 3 of a kind I will feed the 3rd during an event to get the bonus.  I buitl 5-1, 4-1 and 3-1 food that I can feed to keeper champs in the next tourney.  It turned out a lot better than I expected.  

Easiest lego book ever.
