I took a few days off due to the card system and we got a new patch in this time.
What can I say? This is still some kind of misunderstanding for me 
The fact that personal shops that need to be renewed everyday, buying prices are rising in them, is still not the right system in my opinion.
The fact that stones cost 24,000 souls and add 0.3 to attribute is a total nonsense and absurdity. That is fight with RNG?
You can find 4 stones in your personal shop ... Does anyone here know how many stones there are in total? If I count it well 194 !!!, if someone has better knowledge, please correct me.
There are 9 attributes that modify cards !!!
9 attributes and 194 stones! Madness, madness and stupidity, I can't name it otherwise.
My proposition about stones:
Remove 194 stones, add only 29:
9 stones that add a specific stat
9 stones that remove a specific stat
9 stones that INCREASE a specific stat by a SENSE / RANDOM value
1 stone that adds a random stat
1 stone that increases a random stat
In this simple way, we have 90% less randomness, we are not milked from diamonds, and our nerves are fine.
EDIT: And I am begging you, remove these idiotic names and name the stones logically, "Add HP", "Remove MP" etc.
EDIT 2: A stone for 24,000 souls should upgrade the card's parameters to its maximum value. With the current amount of cards (which will increase), 2455 * 24,000 = 58,920,000 is needed anyway, that's probably enough farming.
Again, here is Arcadia, not Casino
