The different card series are there, because in first line it's a card collecting game. And I'm playing with the idea to make older packs more expensive, when I add new ones.
The arena is a gameplay gimmick I came up with, because I like roguelite games and I wanted to make the cards have atleast some use and to increase the coin gain.
And I still see some flaws and room for improvement with the arena mode, like I think I might change the attack / defend order, to not let your first llama do all the heavy lifting and to make the decision between buying equipment and potions a bit more difficult.
