Many thanks for your detailed feedback, much appreciated! These are great suggestions.
Ability cooldown notification and item confirmation - yes! Will do.
Regarding the enemy abilities, they are already very impactful if you're going for the second achievement. Otherwise, the descriptions are rather complicated, it's true. This also relates to the number of cards which are currently balanced towards using your hp pool to get the achievements. Maybe you'd like to go for it? 🙂 Anyway, yes, more patterns and also more hints to existing patterns will follow, since they're not as easy to make use of as intended.
Auto-clearing I left out so far because this game one day shall feature enemy abilities hiding the numbers around them. Let's see it this doesn't turn out to be too frustrating ... thank you very much once more for sharing your ideas!
