"Fight Club" Trading Card Game with Real Time Elem

I'm working on a trading card game with a real time "slap" mechanic with a underground "Fight club" theme.

I wrote a topic about it before, and it got a little off topic and ended up not awnsering the questions I asked in the first place, and I got overwhelmed and so it got dropped. So I thought I'd start a new topic, summarizing the other topic and putting back up the questions I wanted answering and answering the posts there before.

First of all, this game (Let's call it project "Fight club" for now, not the real name) is a trading card game in the tradition of pokemon and magic the gathering. It is NOT a real time game like brawl, but has a real time element for resolving "conflicts". The reason the game is not completely real time is firstly, because real time games don’t seem to do so well market-wise (Like brawl which is out of print) and secondly, because I wanted a more in-depth strategy where the players had time to think.

Card Types

Fighters
Each deck would feature a single fighter, that the player startsa with at the beginning

Moves
The players choose 1 or 2 to put on their fighter at the beginning, the rest go in the deck and are drawn an added to the fighter. There can be only 4 moves on a fighter at a time. Moves can also be removed to empty a space for other moves

Arenas
Arenas are not part of a deck, but are kept separate. The player who goes second gets to choose what arena is in play form their cards.

Slap physics
At the end of player’s turn, they choose an attack attached to their fighter and announce it. We’re not completely sure of what will happen next, but there will be some phase where cards are drawn and when a match of some kind is made, the players slap down. Payers do not simply slap when the attack is declared (That was the original concept, but it really didn’t work)
The symbols on the card will most likely be color coded with the four basic colors, (Red, Blue, Green and Yellow) Rather than numbers, since they are easier to identify. There will probably be other aspects to the “destiny” symbols too, later to be added.

“Just FYI the published game Halli Galli uses a slap mechanic (where you slap a bell first) and seems somewhat similar.”

No my game’s quite a bit different. Hali Galli looks to be a simple quick matching game like Egyptian war, mine’s a more complex TCG with a “fight club” Theme.

Now to my main question that was the primary purpose of my post

Is a slap game marketable for boys aged 10-12 and possibly even an adult market? Someone commented in chat (I think Scurra) that one grows out of “slap!” games. Is this true?
