There should be cards in the Arena Rewards section which can be unlocked after completing challenges. Challenges could include: Win 10 times in a row in Plat 3, Win 50 battles in a day, etc ...
There should be an option where faction members can see which other faction members are online. Or at least faction warmasters/officers/leader should be able to.
Wtf I was sorting my deck and I suddenly lost my Havoc and EMP. I cleared filters and checked. Sorted filter and checked. Checked my other decks. Both are gone. I'm guessing I somehow sold them while I was in the Edit Deck screen? I never left the screen, something happened and all of a sudden those 2 disappeared. Wtf?
