[Pokémon] How can the technology used in the Master Ball ensure that it catches a Pokémon EVERY time it's used? No human technology is that accurate. Is there magic involved? And also: how come they didn't just implement the Master Ball technology in all Pokéballs after it was invented?

The Master Ball is basically the Swiss Clock equivalent to a regular Pokéball. It's made with so much care and masterful craftsmanship that it works perfectly.

However this precision comes with the limitation that it's simply to complex to be made in large quantities and takes years of trial and error to be built. That's why we only ever find one pro region and why we often get it from the regional Pokéball craftsman themselves, they made this one as their magnum opus and only give it to us because we helped them and showed us to be worthy of it.
