Of course individual magic will often be necessary to unlock a compact defence, but it isn't the only tool, nor should you rely on it exclusively. I remember watching a coaching session which emphasized structured possession in the final third, switching the ball side to side, dropping into half-spaces, etc. And the coach said that the aim of doing all that was to wear down the opposition, and eventually provoke at least one defender to move out of position, and hopefully he'll have trained his own players to be able to see that 'solution' the second it becomes available. That's the point of those exercises: have players with the technical ability to keep the ball in tight areas, the discipline to keep doing that despite frustration, and the tactical awareness to see when a gap opens up, and go through it.
If you find yourself relying on magical moments all the time, then results will vary.
