Quagsire and BellyZard Analysis
This strategy includes using both Quagsire's weakness to Charizard's advantage. Setting up Charizard was always difficult but now it is made easier with Quagsire. Here's the set for Quagsire:
Quagsire @ Leftovers
Ability: Water Absorb
EVs: 252 HP/122 Atk/136 Def
Impish Nature (+Def, -SpA)
- Substitute
- Encore
- Stone Edge
- Earthquake
Stone Edge is important to counter Gyarados and Earthquake is just for STAB. You could have Protect over Earthquake to scout they're attack if you want.
Basically switch Quagsire into a water attack or something that can't hurt it like Blissey. Use Substitute on the switch and they will most likely bring out a something with a grass attack. When they attack you will Grass Knot or Energy Ball, use Encore and as they try to attack you again, switch to Charizard who will take the attack with ease and then setup. This is the standard set for BellyZard as it is usually called:
Charizard @ Salac Berry
Ability: Blaze
EVs: 252 Atk/4 SpD/252 Spd
Adamant Nature (+Atk, -SpA)
- Belly Drum
- Substitute
- Fire Punch
- Earthquake
Setup a Substitute when they switch out their Grass Type and then Belly Drum on the next turn which they will break your Substitute. Then hit hard with Fire Punch or Earthquake if they resist.
Other Options:
You could also use a Raichu in place for Quagsire since it can also counter Gyarados as well as using Substitute and Encore (faster as well). Even better, it only has one weakness which is ground, which they will definetely earthquake you with the Pokemon which they switch in (most likely Garchomp). You can encore the earthquake and then switch in Charizard which resists it and continue to setup.
