These are the puzzle answers from this section (given here in alphabetical order):

• GOLDEN STATE
• PEARL
• RED CHINA
• THUMBHOLES
• WOODSTOCK

Each of the five clues has a set of blanks, a product description, and an enumeration with a ™ symbol afterwards. The enumerations do not match up with the blanks. However, the answers to the given Pokémon puzzles do fit!

Each product description obliquely clues a “product name” which is actually the name of a TM (Technical Machine) from the Pokémon series. Each TM has an associated number. (Between the different generations of games, some TMs changed numerical values. The TMs clued here all have the same number in all games where they appear.)

Each TM number is two digits long. Use each digit as an index into the corresponding answer. This gives us the following:

The extracted letters spell out the required technique, BLACK MAGIC.
