Actual problem with the new UI in battle (or maybe not)

There are a number of complaints about how the new UI is displeasing, and I don’t disagree, but this post is not about that. I’m here to point out that the mana indicator for a card disappears while its spell is ready, and this means that you can’t check what colors it uses or how much mana it needs until it actually casts its spell, which seems like an obviously bad thing.

Edit: Actualy, I guess you can click the card and check it on its art, which nobody ever really looks at.
