A strong foundation in anything will have better longevity than a bag of secret tricks. Applies anywhere but this is especially true in combat sports. If you know a move like the back of your hand, then you will be able to execute it regardless of whether your opponent is aware of that move, you will always be able to force that move onto them. Compare this to something they don't know, then once it's found out, the main factor for its success - surprise - is nullified.
