In the collections view, I’d like if there was a filter option for the cards that are eligible in Duels mode; currently the only filters are for Standard, Wild, and Classic. I’ve considered using my dust to craft some cards for Duels, but because the sets involved in Duels change, it’s a bit hard for me to remember which sets are currently eligible. I’d also like to simply be able to see what cards would be available to build a deck for duels, so I can ponder deck designs, without having to actually start a run AS a specific hero in order to see what I have available for it.
