2 V 2 Gamemode.
Hanger showdown was very much needed. The rewards are not the worst, but could definitely become more significant. I do believe that the rewards should include 5 Fortune Keys instead of 3, and should give 100 a-coins. I also believe that it should reset every 12 Hours instead of 24. Of course, people will not be able to play every single time, but it is better than waiting 24 hours and then finding out you have no time to play.
Though, I do think you should bring back 2 V 2 Showdown. It would fit well with Hanger showdown being present.
