if all the cards are the same the only option is their "usage". I would like to see cards utilized in the same way as they used to be pre ShB but expanded. Some examples off the top of my head of how cards can be utilized in different ways while still staying the same dmg buff as it currently is in EW:

-Set: Place currently drawn card face up on the field. AoE buff bubble for those standing in it on a long recast.
-Minor Arcana Set: Place Crown Card face down on the field. AoE that acts like Earthly Star, where the longer it stays the more potent the effect and will flip face up when timer ends. Lord is dmg, Lady is heal.
-Undraw: Return card back to the deck and resets one Draw charge on a long recast.
-Spread: Target player's current card effect is spread to nearby players. Duration is based on current time of the card of target player.

Some of these examples change how you use the cards but the cards themselves are all still dmg up buffs. It's one way of reducing that feeling of homogenization that the cards have become. While I do prefer the pre ShB cards I can understand that the change is needed to bring in newer players and that is always something I can get behind (to an extent). Though you have to admit some of the examples I made would be pretty cool to see.
