I’m an idiot!!!! But a lucky break!

So I’m playing Pokemon Leafgreen and battling the Elite Four before they become really strong. I just beat Lance pretty easily and almost all of my Pokemon are fainted or damaged. So without thinking, I go into the champion’s room. Luckily, I had my legendary Raichu first which takes out almost everything it battles against. So lucky for me, I was able to heal all my pokemon while he didn’t switch out to his Rhydon. His Pidgeot was wasting its time using sand attack (which you learn at like level 5 and it’s lv.59) and my Raichu knows Shock Wave, which never misses and took it out in two hits. After that I kicked the stuffing out of him and won!
