I just found out that Kiki-Jiki, Mirror Breaker has been added to the game—someone played it against me! The problem is that this card—like many other individual cards you add—isn't listed under any set in the search tool. I never know when new cards are added. You really should include a "recently added" or "latest cards" section; I understand that you wouldn't create a specific filter for a set that only contains a few new cards, but forcing players to hunt for them manually via the search tool is unprofessional. You need to highlight what’s new. Furthermore, the search tool itself is completely outdated. Also, when you view a card in full size, there’s no indication of which set it belongs to, making it hard to look up. It would be great to have a code or an in-game feature—like a "favorite" option—so that if an opponent plays a card you don't recognize, you can mark it and find it easily later. Whenever someone plays a card I didn't know was in Arena, the first thing I want to know is: what other cards have been added?
