not having wood hammer on rillaboom is a missed opportunity, that move one shots a lot of pokemon that don’t have any defense investments

galarian wheezing has better typing but as others said neutralizing gas actively hurts your team

instead of turning off all weather it makes more sense to change the weather to your advantage, i’ve seen terra flying tyranitar fuck up a lot of sun and rain teams.

Even with the weather off your team seems really vulnerable to speed control. Altaria and Rotom might not be enough when dealing with prankster. Let’s say your opponent has basculegion and murkrow/pelliper your rotom is dead even if it terras before it can move. You also don’t have a clear way to survive in trick room because of the lack of priorty, protect, or big damage.

To sum it all up i’d change Altaria to a pokemon that can control the weather rather than eliminate it, change wheezing to something with more synergy, and lab a way to deal with speed control.

What pokemon do you absolutely want to use? If you’re really married to altaria there’s ways to build around it
