@ Tobias mann :

Yeah, I was surprised to get 4 CREs from my Advanced Box. I had "expected" only 3 (being the middle between the "pro 4" and the "rookie 2", but others seem to have got 4 too.

And yes, it's never carved in stone, except for descriptions like "At least 10 will be Rare or Legendary" where you can be sure about the minimum of rare or legendary cards.

As I haven't heard of people who got no engine at all in a trophy reward box, I think, however, that these boxes have an "internal" minimum, too, that exists but is not communicated. Or the probability assigned to the event of 0 engines is so small that it practically never happens.

That's why I played the championship. I knew they'd raise the probability for engines in their boxes and that I wouldn't be able to collect so many of them in such a short time in the near future again.
