Okay, even though I am a 12 year old, I have vast Pokemon knowledge. Stats, IVs, EVs, everything. Here is my regular Zard variant.
Charizard @ Life Orb
Ability: Blaze
Tera Type: Dragon
EVs: 252 SpA / 252 Spe / 4 HP
Modest Nature
- Fire Blast / Overheat / Blast Burn
- Air Slash / Hurricane
- Dragon Pulse / Tera Blast
- Roost
The plan is simple. Life Orb adds even more power to Its Fire and Flying STAB. If you want a hyperattacking variant, and don't mind sacrificing a bit of HP or power, Life Orb+Blast Burn+ Hurricane is the set for you. If you want to play the long game, and are building the team around it, Flamethrower + Air Slash is perfect. Dragon Pulse provides STAB for its Dragon TT, with Tera Blast also being a good option. You may or may not run Roost, depending on yr playing style. You can also alternatively run two Fire moves instead of Roost.
