With the addition of Volcanion and it's much appreciated utility, it also adds a weakness to Electric that shouldn't be ignored. Being as this Fire team utilizes Fletchinder, Scarf Heatran, and Roostless Zard Y, it is much easier for Electric to apply pressure to this team than the old standard Fire team. The mons are presented below:
Raikou @ Choice Specs
Ability: Pressure
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Thunderbolt
- Volt Switch
- Hidden Power Ice
- Extrasensory
Rotom-Wash @ Leftovers/Chesto Berry
Ability: Levitate
EVs: 248 HP / 152 Def / 108 SpD
Bold Nature
- Volt Switch
- Hydro Pump
- Will-O-Wisp
- Pain Split/Rest
Ampharos @ Ampharosite
Ability: Static
EVs: 248 HP / 28 SpA / 232 SpD
Calm Nature
- Volt Switch
- Dragon Pulse
- Rest
- Sleep Talk
With the combination of these 3 Pokemon(+Zapdos), this team will have a hard time dealing with the switch initiative and coverage/power these Pokemon utilize. Rotom-W/Mega Ampharos form the core that'll deteriorate the team with their Volt Switching or pummeling with their coverage move. All the switch initiative allows for Electric to safely switch into a Pokemon that can handle the Pokemon in front of you, so there isn't a real need to over predict much against this team. Rest recovery on the two mons also increases their longevity so they won't be worn down and eventually taken out. All this leads t the nuke of the team, Raikou. With Choice Specs equipped, Raikou will 2HKO/OHKO everything after coming in from Ampharos'/Rotom's Volt Switch, with nothing to really outspeed it except ScarfTran, which is walled by Rotom-W. One thing worth noting is that even though these 3 Pokemon work fantastically in lowering the health of this team, Sun boosted Fire Moves and Hazards are still a pain to deal with, so Defog immediately with a Zapdos that can come in on something it can outspeed/wall(Entei/Fletchinder for example).

If only Magnezone could set up hazards... But yeah, with Team support from Zapdos and Magnezone, these 3 mons can be a huge annoyance for a team like this. Note: I did not add Fletchinder in any of the calcs as it an be handled very easily by the rest of the team (Zapdos and Mangezone),
