Any detailed Ultimate Team information?

[pokerplaya]

I mean, I think I get this mode - I start off with a bunch of crap cards who are my players, and I assume I win games to buy packs. But how much are these packs, and how many coins or whatever can I hope to get with a win? Can I get any points if I get smoked? Does this EVER cost any money to compete?

I'm sorry, but EA's explanation left some to be desired and I haven't been able to search for any quality info. So even a link to some detailed info would be greatly appreciated. Thank you!
