If they were just sitting around there in plain sight, why doesn't every villain simply grab them and use them against the gang? Gee, why doesn't any villain use them to create portals through time and eliminate the gang like Emily Green intended in Time Turmoil? The fact that the black crystals didn't steal the spotlight during season 4 is a confirmation that the black crystals can't just be sitting around in plain sight everywhere.

That can't work either. At the end of Time Turmoil (when Emily Green becomes good), the gang decides that the best way to make sure the black crystals don't fall into the wrong hands is by destroying them. So whenever they find black crystals, they destroy them by making the black crystals shoot at each other. There's no reason why Ace would suddenly stop destroying them and instead start accumulating them when the gang has already agreed they should be destroyed.
