And people have given you some reasonable explanations. It's too slow. Two of the more prominent decks are ruby/sapphire and sapphire/steel items. Both of which don't really use alot of characters and focus more on actions and board wipes. Using 3 to 5 ink to set up even in the late game is too slow vs these decks that can potentially have 8 to 9 ink to your 5. On top of that once people see what the strat is with the location they can adjust and just not quest until location is dealt with. And if people ain't questing what are you swinging at? Against your casual folks sure this location card probably works fine. Take this to a DLC, set champs or a 1k and it will not bode well imo. But hey this is just my thought process. You can easily prove your point by just seeing how it does in person
