[2020] Let me edit my war decks when their on cooldown

we agree. so for this situation we are working on a solution that is either

1. when all decks are on cooldown, you can edit decks (your current situation here)
2. all cards have individual cooldowns (not ideal)

to me it seems seems like overcomplicating the feature.

i also think if you can't switch cards with active war deck cards it may not have as much impact and you may have to wait for another deck to get put on a cooldown anyways to get the full customization that you want.
