Soloed FB/Psyshock Jynx
I found a Jynx after building my squad, I thought for a while, it was sunny, why not? I went and saw that she had FB/Psyshock, one of the easiest ones.
First attempt, it seemed to be a close one, but my "muscle" really didn't think it would success at that time and hit the escape button lmao.
Second attempt, a Psyshock hit before the first Overheat, and I didn't manage to dodge it, so I failed.
Third attempt, I felt that the RNG was on my side. The Overheat got off first. Then onto my second Pokémon, Psyshocks were delayed, so I was able to use several Flamethrowers. Yellow by 116. Red by 77. Finally, on my Pinsir, Jynx was down by 31! I used a team of 3 Flareons, 1 Houndoom, 1 Pinsir and 1 Tyranitar.
I think the key was getting off Overheat first and not being hit by consecutive charged moves, maybe next time I can do it without the weather boost with better dodging.
