How to handle deprecated cards

[oskarrough]

If a card is removed or renamed, no longer with us let's say, any runs referencing this card will fail.

Like here:

http://localhost:4321/stats/run?id=7
http://localhost:4321/stats/run?id=170

For example, the upgraded version of Soul Drain used to be named Lower Soul Drain. Today it is called Soul Drain+. Or we had a High Succube card. Today it is called High Succube+.

How do we want to deal with this?
