If you're running a budget build debuff deck then keeping the AoE Healers and the atk debuffers is a good idea. Examples are Angel and Ginger.

If your don't have a good SR AoE damage dealers, then you can keep a couple of the 15%/20% Aoe damage dealers such as Arch Knight. These are useful in duels and in campaigning.

20%/30% timeskips like Pinocchio are also worth keeping for duels and campaigning.

You can also keep 40%/60% EXP up cards like Star Reader. You can use them to level cards by last hitting AWs with one or two of these in your team.

And I don't think any of the other R cards are too useful. I ran Shaman for a long time, so I can see the reasoning for keeping other R buffers, but once you get your hands on a SR 200% AoE buffer, then it'll outclass any R cards badly.

Other than that, I just keep the cards that I want to collect and medal the rest.
