My play deck of eight cards right now is worth 33,000 clintz if I sold them at the lowest market prices, how long do you think it would take to build up that deck at 1000 clintz per 10 credits? You may not always pull rare cards from packs, but in the long run your way better off buying packs. I have pulled tessa, Dorian, nisarock, and many other awesome cards out of about ten packs. The tessa card would have cost me 120 credits by itself, at 10 creds for 1000 clintz.
