What card modifiers stack?

[Shedletsky]

I found a steel card with a gold seal in a booster pack, so I figured, hey let me use this tarot card to add a gold seal to my lucky ace. But the lucky modifier got overwritten and it's just a plain gold card.

This is fairly frustrating. I have no idea which modifiers will stack and which won't.

Maybe the UI should tell me before I commit to burning a tarot card to upgrade something that won't upgrade.

There are three categories: Enhancements, editions and seals, each card can only have one of each. So for example, you can have a Foil Lucky seven with a red seal, just check the collection, you'll see a separate section for each.

I think the logic goes:
Enhancements affect and change the card itself;
Editions are more valuable alternate versions of the card, like in Pokemon packs;
And Seals are probably some appraiser thing, but only the most recent appraisal can apply to the card.

You can always go Options --> Collection --> Enhancements/Editions/Seals mid-run too to see if there's an exclusivity conflict
