I love single Pokemon challenges in this game specifically because of the Pokemon actually following you around. So cool and helps you bond more with it
Vulpix is such an adorable little killer - I have a feeling that Red might be possible - with double team. But it would probably take a ton of attempts because the luck needed is insane.
You talk really fast. I noticed it particularly at the Elite 4 and it often leads to moments of dead silence. Would probably be ideal to only keep in the successful attempt or continue where you left off after a loss.
