Wait, 1 DEC is not cheap for you? It's currently 1700 DEC per $1. Wait wut?
I don't mean to be rude but if 1 DEC or $0.00074687 rental is expensive for you. I do think you have to find another game. One where you can rent a card cheaper than $0.00074687.
I am thinking at bronze players for example, in bronze you earn 0.00x sps per win, if prices that were 0.1 now becomes 1.1 daily, you think that's sustainable for the player? Of course not, a full set is gonna cost just too much
