Wasn't prepared for jynx
I finally came upon a jynx raid today and I was pleasantly surprised! I couldn't beat it ! I have since powered up my team and I can't wait to try one tomorrow. Level 36 and I don't have any entei or moltres so I had to roll with a team of level 30ish flareon.

Dark is even better. Fire Fang+Fire Blast is already a couple notches down from the best fire moveset. Snarl+Foul Play, if I'm not mistaken, is the current best dark moveset on any pokemon (theoretically it could be bite+foul play but doesn't exist)
EDIT: Dark moves referring to Snarl+Foul Play only, not Crunch
Houndoom is a great shout as it resisting both ice and psychic, although from the psychic side it will probably still be worse than Ttar
Flareons- do they have fire spin and overheat? If you're fighting an exclusively ice Jynx, it doesn't get much better than that for non-legendaries. Ttar and houndoom could be on the slower end, and end up marginal, but they still beat the clock.
