**A. Simple Shuffle (Most Common & Effective for Simple Games):**
   - This is the easiest and most effective approach for most cases.  It involves re-generating the sequence of function calls.
   - **How it works:** It uses the `rand.Shuffle(n)` function to randomly reorder the generated sequence of function calls.  `n` is the number of functions to shuffle.
   - **Code Example:**

     ```go
     package main

     import (
         "fmt"
         "math/rand"
         "time"
     )

     func Monday() {
         // Example: Create a list of 2 functions for a weekday
         groundZero()
         functions := []func(){
             func1(1) { Heroine() },
             func2(2) { Cocaine() },
         }

         // Seed the random number generator for more variability.  Important!
         rand.Seed(time.Now().UnixNano())  //Use a unique seed value

         // Shuffle the functions.
         for i := 0; i < len(functions); i++ {
             indices := rand.Perm(len(functions)) //Generate random indices
             functions[indices]() //Call the function at the randomly chosen index
         }

         fmt.Println("Randomized Functions:")
         for _, func := range functions {
             func()
         }
     }
     ```
