@ Geohey:

I think you are assuming something that isn't defined anywhere either: "Common" only means that a common card has a higher probabilty to appear than a rare or legendary one. This does NOT mean that all common cards have the same probability.

You could deduct this to some extent with statistical methods if you had written down ALL cards you got since the very first box you opened so that you have a population big enough to draw conclusions. You would have found that common class D, C and B parts appear more often than common V8 and i4 engines.

So, "common" could be defined as having a probability of 70 %, but the relation of parts to engines cannot be concluded from this number. If engines had a probabilty of 20 % and parts had a probabilty of 50 %, the overall probabilty of "common" would be 70 %. There again, Gameloft doesn't tell us.

By the way, that's the reason why you get more points when you fuse an engine than when you fuse a drivetrain. Maybe it's even the exact ratio. Just a moment, I'll see. A class D, C, B part grants 500 points now, a common engine 1,500 points. That's a ratio of 1:3, so my guess of 2:5 (20:50) was quite close.
