There was an idea that I pitched long ago as a suggestion for how the card system could be revised. It may need to be updated in light of recent changes, but the gist of it was that we would have three cards for offensive support (examples: damage, crit. rate, crit. damage) and three cards for defensive support (examples: damage reduction, healing received, regen). In the event you draw something that you don't want, like a defensive card when you need offense, you can use Minor Arcana which would "flip" defensive cards into Lord of Crowns and offensive cards into Lady of Crowns. The objective behind this proposal was twofold: Bring back variety in card effects while simultaneously achieving consistency with results. If you want every single card to contribute damage, you can do that. If you want every card to assist with healing, you can also do that. Or you can play both and adjust to the situation as needed.

This system would probably not work the best with the existing seal system which, in my honest opinion, should be scrapped. I didn't like it when it was announced and it never grew on me. It feels bad when you draw Balance back-to-back, but you shouldn't play the second Balance because it matches the seal you just received. If they want to keep the seals, I would suggest having cards grant us a seal we don't have regardless of what card was played. Once you play three cards, you'll have one of each seal. Always. No more "fishing for seals."
