Not a counter because Magma Storm has a decent chance to KO Mienshao on the switch-in and if it survives, the residual damage from Magma Storm will finish it off. Bloom Doom also outright KOs it.

Will counter Heatran:

Charizard Y:

-Fire Blast
-Solar Beam
-Focus Blast
-Dragon Pulse
Nature: Timid
EVs: 4 Def/252 SAtk/252 Spe
Item: Charizardite Y

Mega Charizard Y's typing and surprisingly good special bulk let it wall the entirety of Heatran's moveset, then threaten it with Focus Blast

Chandelure @ Choice Specs
Ability: Flash Fire
EVs: 248 HP / 252 SpA / 8 SpD
Modest Nature
IVs: 1 Atk
- Hidden Power [Rock]
- Fire Blast
- Energy Ball
- Shadow Ball

Dragon Pulse cannot 2hko, while HP Rock OHKOs in return.

Honestly the Zards are pretty hard to counter, but I wanted to post something more creative than some fat tank. So max HP Chandelure lets go

Hippowdon @ Choice Band
Ability: Sand Stream
EVs: 252 HP / 252 Atk / 4 Def
Adamant Nature
- Ice Fang
- Earthquake

Raikou @ Choice Specs
Ability: Pressure
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Thunderbolt
- Volt Switch

Without Specs, Volcanion does not have the power it needs to pick up important KOs and allows Raikou to survive any attack and then outspeed and KO with Thunderbolt.

Jolly Nature
