Click taunt vs pex and you should win the 1v1 (Fire spin is an option if you want to snipe pex more reliably)
252+ SpA Volcanion Steam Eruption vs. 248 HP / 220+ SpD Gliscor: 354-416 (100.2 - 117.8%) -- guaranteed OHKO
252+ SpA Volcanion Earth Power vs. 248 HP / 228 SpD Toxapex: 136-162 (44.8 - 53.4%) -- 32.4% chance to 2HKO
This also does well vs common steel types that are usually paired with Gliscor and Pex (like ghold and ferro)
