I look at all the choices i have: Basic, New Blood, Extended, Elite, Silver, Gold, Ultimate, and Titanium.
I'm having a hard time deciding which one to pick. Which one of the booster packs is best to pick based on getting cards that are useful and cards that can be worth a lot of clintz that can be used to buy high priced cards?
Ex: Tessa Cr
None! Tessa Cr is a Collector and cannot be found in packs.
If you're looking for "useful and cards that can be worth a lot of clintz", I'd say go for the ones that offer rares. Of course, Titanium is your best buy since you can choose the 4 clans that your cards will belong to but it's on the costly side (295 credits) so you can also opt to buy multiple of Gold, for example.
