Physically Defensive Chesto-Rest Rotom (Wash)
Rotom-W @ Chesto Berry/Lum Berry
Bold Nature (+Def, -Att)
252 HP, 252 Def, 4 SpAtt
-Will o' Wisp
This set excels at checking dangerous physically inclined threats like Gale Wings Talonflame by coming in on a resisted hit and either Volt Switch while they get forced out or Will o Wisp to burn. Rest is to heal off status and fully restore health. Hydro Pump to smack Talonflame, Tyranitar and the like. Against Blaziken, this is an excellent way to bait Blaziken into using High Jump Kick, before switching into a ghost to make it lose half its health.
