Alternate cash shop

Slytechs

Given the current odds of pulling anything decent after having bought quite a few boxes (upwards of 20...), it would be nice to have some sort of alternate way to get those few cards that we are missing in our decks. Maybe create refreshable Cash or Crystals shop for Mythics and Rares (like a choice among 6 different ones, 2 Mythics, 4 rares), containing only singles that rotate every 24-48h? Also, maybe add the option to convert Crystals to Runes or vice-versa?

I'd love to see a new type of pack which contains one card you don't already own. It might be common, uncommon, rare or mythic, but you do not own that card (unless you own all the cards).

If they had a product like that, I think people would gladly pay crystals, runes or cash for it.
