Do we really have have a need for specific-card? It seems like an extremely broad tag that could apply to most questions on the site involving cards.
Currently it appears to only be applied to one question and I think it should not be used at all.
This has now been applied to a question with no other tag to support it so I think there is strong evidence that this tag will be misused.
Mini Rogue - What player get After defeat Boss Monster at area 11,12 and 13?
No, specific-card should be removed.
The tag "specific card" divides all questions on the site into two categories: questions about a specific card, and questions not about a specific card. Neither of those categories is useful.
Furthermore, any guidance on when to use this tag will be extremely dicey. The majority of questions about individual cards get resolved using the comprehensive game rules; i.e. the real question is about the rules, not the card. There is a very fine line between a question about a specific card and a question about the rules that happens to apply to a specific card - too fine to justify a tag that delineates it.
No, the tag specific-card should not exist. The purpose of a tag is to label a category or topic that someone would either search for or watch. This tag does not do any of that, so it should be removed.
UPDATE: I have removed the specific-card tag.
To add another reason to the other 2 answers... the primary way I use tags (and I would guess most people do as well) is to know if a particular question is one that I might be able to answer. Oh, this question is about MTG, Dominion, Catan? I know those games well, I should read this and see if I know the answer.
Subcategories of MTG succeed in helping with this as well... Some people might know MTG rules pretty well, but don't know much about Commander. However, it seems very unlikely that anyone out there would be able to answer a question that's about a specific card, but not a general one. Or that would be able to answer a general question, but not one about a specific card.
I disagree with the others!

"specific card" is not a tag I search for to see if I can answer questions. But it is useful to get a feeling what the question is about, and if I am likely to go the extra mile to make an effort. True, often questions regarding specific cards can be answered with a reference to the rules, but this is because the card is part of the game!

This is your personal opinion and not a fact. Counterexample: "reality-check", "science-based" and "hard-science" on Worldbuilding SE. Divides the questions on the side into 3 categories and it works good for them.
Nice quote from relevant question on meta:
Tags that no one cares about are not harmful. Removing a tag that someone cares about is harmful.
