I adore the artstyle and really like the gameplay so far (just played the demo on steam)
But I am colorblind and it is really hard to differentiate between the higher rarity cards into exploration vs combat decks.
I'm guessing what is grey to me is greenish and redish for non-colorblind people. It would be nice if they had a diferent border, texture or maybe like one corner is folded over for exploration cards.
I would also love if the amazing artteam would use what they already do to make cards look unique (the border of the card being different, like for the scream card, the card being mossy for the moss regions) to uplift visual clarity. Legend of Runterra cards give you a direct visual if this is a skill, attack, food or mood and something like that would help the game a lot I think.
But the big thing for me is the color-blindness, because especially with food I often don't know which deck I'm adding it too.
