A good way to be unpredictable and still play to strengths is this...here's an example of how I do it.
You just sprinkle in PTB, BO, or II to your steady diet of LI or LP. One guess won't kill you. Switch it up...then don't...once you establish that you switch do the same thing 3x in a row...then start switching again.
It's easy to be unpredictable but still play to an inside strength. If you are an outside team do the same thing only with Motion and RNG.
