User blog comment:Guy Bukzi Montag/Asphalt 8 Myths: Cards Come to Those Who Have Them/@comment-24458118-20190124125028

That golden rule may not be true, but this game sure loves to stick to certain cards and not give anything else. I swear I could've built the 4C and Torq three times over in one month. Just from opening boxes. I've never seen a high-grade engine or a Hot Wheels engine, or others, and they're all supposed to be equally rare.

The game obsesses over a few cards and bombards you with them while not giving you anything else. Maybe a second golden rule?
