I can't make the icon more prominent without giving it a background that covers up part of the deckbuilder, and I'm not particularly fond of doing that. If you ever played Long Live the Princess, you'll know I'm a fan of minimalism when it comes to interfaces. Unless your experience becomes a recurring thing with players, I'm not too worried.I enjoyed the card battling aspect so much that I ground out all the cards almost by accident with only 2 decks. One for Vanguard and one for Seraphim
When building a deck it would be nice to separate out cards by type (Engine, Instant, Attack) and by stat (Confidence, Skill, Trust) so that it's easier to focus deck building without memorizing the name of the cards.
I really want to be able to compare Skill Engines, for example, or see all the damages available to me when attacking Trust, or sort by Heat cost, or filter by rarity. Really anything to make it easier to deck build without having to scroll through a list and reread every card in the hopes I'm not forgetting anything.
I really enjoyed the challenge of the card game, and the ability to scale challenge and reward together. I just found it difficult to deck build with so few filter features.
I am eagerly awaiting the next release! I've enjoyed what exists right now and I'm excited to see where this goes.
*edit* And now I boot up the game and open the deckbuilder and notice the little button in the lower right that has all the functionality I was asking for. So I guess I'm just asking for the filtering to be more prominent or a 2nd button that says "Filter" or some other cure for my own oversight. */edit*
The filter was actually added recently and wasn't around in the first few versions. Implementing it was far from trivial and required an almost complete rewrite of the way cards are presented in the deckbuilder. Still, it was worth it, and the change came with the ability to sort cards by any metric I want (currently only alphabetical).
