Well, with the introduction of new characters with every passing week or so, the probability of finding a particular card (whether it's rare, uncommon or even common) decreases with every introduction.
My story's similar to rogues, I had bought
Kinjo and
Methane when they were cheap (simply bought them as they were rares, and I knew their prices would soar in the future). I was not able to sell or trade either publicly or privately because
the shop feature isn't available in my country, but the friends I had made in this game purchased credits for me and they would occasionaly drop in a card (thank you, you know who you are).
Sorry, I got drifted away. Concerning the Crs, I don't imagine even in my wildest dreams that I'd be able to obtain them. So, now-a-days Im collecting as much characters from Soleil as I can, hoping that they'll be worth the investment.
Gg ... always.
