My challenge has been completed. On June 2nd I was able to defeat the Elite four and my rival (named Blue). It was my PIGEOT that dealt the final blow to his level 65 Venusaur.
My team before I made the attempt was:
LEVEL 62 GYRADOS
LEVEL 42 POLIWRATH
LEVEL 37 CHANSEY
LEVEL 51 PIDGEOT
LEVEL 37 OMANYTE
LEVEL 28 BEE DRILL
(I think it was a guy online or maybe on Quora who suggested this weak team). Nobody on my team knew how to use: Earthquake, Thunderbolt, Ice Beam, Blizzard, or any Psychic moves. Also no TRI ATTACK and NO rock slide. My team really did not have that much HITTING POWER.
My main pokemon were the GYRADOS and the PIDGEOT! They were able to deal damage. Once I evolved my Poliwhirl into POLIWRATH then he became more useful as well. BEE DRILL was kind of useless most of the game. And Chansey really is not that great.
I used GYRADOS to beat most of the Elite Four. it knew Hyper Beam which I upped to 7 PP. Lorelei has a tricky team if you don’t have a good electric pokemon, she was a tough first hurdle. Fighting Bruno was pretty easy, just need water moves and flying moves.
Agatha was tough because her team used lots of CONFUSING moves so that was annoying. LUCKILY, in this game only NORMAL type moves don’t hit ghosts, so I could still use fighting type moves and flying type moves and bug moves to hit them. So I actually did use BEE DRILL and Chansey and Pidgeot to beat her team.
LANCE was super easy, I used my Poliwrath on his dragons and they would not attack they only wanted to use AGILITY. And then his D R A G O N I T E was easy to kill I could use Poliwrath and BEE DRILL. (THE AI in Gen 1 is pretty stupid in general).
and my rival was not that difficult. I was able to one shot his ALAKAZAM by having my Gryados use BITE. so that was great.
HONESTLY, the first one, Lorelei, was the toughest because they had good stats and I did not have any super effective moves to hit with.
It was a grind for sure but I am glad I could complete the challenge (which I placed on myself).
I hope the good people of the world will continue to enjoy playing pokemon, especially Gen 1 and Gen 2 games (they are my favorites).
