Quite a few cards have had their artwork "edited" to date, and quite a number of premiums have been downgraded for various reasons.
There have been some "explanations" given along the way, usually after long periods of radio silence in the face of increasing unhappiness from players.
Ultimately, CDPR can do as they choose, but whatever the real reasons, it means that I can no longer trust that artwork that I enjoy will remain as it is. This is particularly annoying when you spend real money to get it - e.g. buying meteorite powder to transmute a favourite card because you like its premium version. As a consequence, I am far less likely to spend real money on things which can be spoiled at any time afterwards.
Incidentally, let's not forget that some cards we acquired, the leader cards, were taken from us entirely, without recompense. I do miss many of those, particularly the premium versions. Even if they do return (and are unedited), it will be a bit galling to have to buy them again, especially at 800 powder each for the premium versions. I very much doubt that I will spend real money to do so now.
The game still has plenty of great art, but it's a shame to see it being compromised, whatever the reasons. It might also hurt the game's financial viability if players are dissuaded from spending money in future because of this.
