Why this matters

The final slots should answer specific questions raised by testing. They are where a promising core becomes a tournament-ready six.

A practical approach

Use this as a focused testing loop. The goal is to make one part of your decision process clearer before adding more complexity.

• List the three matchups that currently feel hardest.
• Add a slot only when you can name the lead, switch, or endgame it improves.
• Retest common matchups after each addition.

Example to test

A sixth slot that enters one difficult matchup with a clear purpose is often better than a flexible Pokemon you never bring.
