Trading Cards?

[Hiirichu]

Hey,
Does anyone know how frequent this game procs Trading Cards? I've played it for 4 hours now (40-something % complete according to the starting screen) and haven't recieved a single card yet.
I assumed I should've had at the very least 2 cards by now.. Is it just an extremely slow proc?
Thanks!

Sign up for steam client beta. If you are already using the beta client, opt out to fix it...

I turned beta client off and recieved a card after 1 hour of playing. Might just be a coincidence though. Will update once I get a second card (quicker, hopefully)

1 hour later and I got my second card, so it seems to have worked. Thanks!

1 card per hour, I think. Maybe per 2 hours...
