I know I've heard some discussion about adding it to RMT, but as far as I know, that hasn't been done yet.
For example: If I ask a question about What are the best strategies for the cards released in the [expansion name] expansion?
or
Is [card name] [expansion] good/relevant in the current TCG? or Which expansion's cards/cards in general are best for [Task]?
or
Why is the [deck name] theme deck good/Why is the [deck name] deck good/how to use the [deck name] deck good/What do I need to change in my [deck name] deck to make it better?
I know there are not a lot of TCG players on the database, but having these questions be somewhere at all will attract such users to join (and may help me out in the future).
And as I know someone will ask: Why does the TCG matter? I'd say, It does for 2 main reasons.
A) It is part of official Pokemon, and this website has official Pokemon content, does it not?
B) Because it matters to some people who like, care about, or play the TCG (like me).
And as always, Thanks!
Suggestions when this content is more frequent:
Include that users should specify Unlimited, Standard, Expanded, or Legacy (or Theme Deck, but that can't really be changed unless it's played in one of the previous). These are usually the "standard format equivalents". (I can explain these a bit, or you could look them up)
It is good to keep in mind certain non-obvious official rules rules (aside from the games default rules) like you cannot have a Professor Sycamore card and have a Professor Juniper card in the same deck. (The Pokemon Company did this because they have the exact same effect, so bringing both would be like bringing twice as many copies of the same card).
Include availability. If a player wants to choose between certain cards, they should include if they'd be able to buy another if it were suggested and they didn't have it, just to sort out confusion between the asker and the answer-er.
Edit: as well, include if they're playing TCG online or IRL.
