Maybe @Brigby or @Ducky (I’m stull not sure on what the responsibility of Moderators vs Administrators is) can move it if it’s not, but can we exchange 5* duplicates rewarded from 4* championing like we do from Latest packs?
If so, please remove this. If not, then that is my suggestion 
example (cause it just happened to me):
My Black Bolt is at 3-5-2. I just leveled my Medusa to level 300 without paying attention and she rewarded me a Black Bolt “black” power cover. I can’t use this. Even with Black Bolt set as my favorite, there is no way in Hades that I’ll get 3 draws to get him to 13 powers before the one I just got withers on the vine. It’d be great if these could be exchanged via Customer Support as well.
