I get up stealth rocks on first turn with sturdy Golem.. eliminating the field effect is impossible.. I looked at the field effect guide and decided that Explosion on Golem would be best to get rid of the superheated field, but it didn't work for some reason, it just stayed the same. Can't really find anything else to get rid of it.
I like it but one the trick room's reverse priority, and it would die on first turn because typhlosion=sonic.
Mine is the level you find it when you catch it. My pachirisu knows it but Sonic Typhlosion outspeeds it
Edit: Finally beat her! Didn't have to level anyone up either. Used Rain Dance with Prankster Sableye, stealth rocks with Golem. I reset until Darmanitan didn't use rock slide. After he sent out ninetails and it got the drought, I just used a revive on Sableye and got another rain dance then Greninja sweeped out the team with Water Shruiken from there,
