Mega Houndoom VGC Team Build | Pokémon Champions

https://pokepast.es/c8f45bc795dd3966
The team focuses around mega houndoom, for those who don't know and dont have time to do researches, it gets 140 special attack, 115 speed and solar power. I need help to make it better, any advice is appreciated.

I paired it with rillaboom to help it survive atleast one earthquake from garchomp and other common earthquakes spammer, it also gives it back the health it looses with the sun because of solar power. And boosts its solar beam. (Also I need it to terrain war against other's psyspam)

Next is torkoal, for obvious reasons, he's here to set up the sun for houndoom and blow holes inside opposing teams with its powerful eruptions. Just like houndoom he likes the halved earthquake powers. (Also need it to counter opposing weathers)

Farigiraf is the trick room setter which torkoal need and helps against priority. There's nothing else to it.

Dragonite is my tailwind setter, which houndoom and rillaboom desperatly needs, he threatens charizard well with thunder punch as most of my pokemons cannot ko it at all unless they double it.

The final member here is sableye. I needed another support to give my team the help it needed but I didn't want to add whimsicott as this would give my team another grass type that wont even take advantage of the grassy terrain. Sab just speed control with quash and fake out and it can use sunny day if I feel like torkoal would be bad in a certain matchup or if the weather gets resetted.

Anyways, I feel like this team needs alot of improvement but I feel like Mhoundoom can really shine with the right teamates especially in the current meta since it can ko both indeedee and rillaboom.
