I started fairly early in Untamed and my suggestion for new players is not to buy pack if resources are scarce. I is better in my opinion to purchase specific cards. My experience with packs is half of what I open I hardly use because I have a bunch of cards of low levels where if I just focused on a few cards I knew I wanted I could level them up and make them very useful. Since you're renting you probably have a few cards that you like that you rent. I you started using you DEC or whatever else you have to buy and level up those cards you can slowly start not needing to rent them which will become to leave you more DEC to use to buy more cards and so on. With CL out now you might be able to buy specific CL cards for cheaper than Alpha or Beta that basically do the same thing now too. I used to rent Flesh Golemn even though it's an expensive one because it is so good. But now I took that DEC and got Pelacor Mercenary which is very similar and don't rent the golemn anymore. That's been my approached and as helped me as I don't have much going in either.
