View card variants in Card Details Page
When viewing the detail page of a given card, the user should have the ability to view (or click to see a filtered search result) other variants for that card. This would help collectors identify the right variant for their card, which can often look quite similar especially for unnumbered cards.
This is similar to a request I've had in the past. I think this would be great. For me, the value add comes from when I search on google to find a card, but a different variable is found in the search results. I can still click the link that takes me to Sportscardspro.com, even though it's not the parallel I was looking for, but then I can easily find the right card.
To add on to that feature, it would be cool if the parallels had a "+" to add to my collection.
