I know this is like, super niche but I like to use controller for games so I don't get an RSI. Problem is the Rip pack really does not work with this as I have no right-click equivalent for it.

Pressing the B button on xbox (O on playstation) controllers is just 'cancel,' which does nothing if you're not currently preparing to play a card. Perhaps that could work? Or maybe even pressing in one of the sticks, as clunky as that is, because then it would work in the UI for the relics that give you cards from other packs.

Of course, it's possible that doing this would lead to mouse users having incorrect inputs, which if that's the case then I guess it may be unfixable.
