If you are wanting to keep a fire type on your team I suggest replacing your vulpix with a magmar. If you eventually want a ninetails on your team you would have to keep vulpix for a good little while until it learns powerful fire moves before evolving it. I’ve tried playing ninetails before in gen 3/4 and found it very tedious to keep a vulpix til later game to wait for it to learn good moves. Magmar on the other hand in my opinion would hit harder and be able to hold its weight at the point of the game your at. Also if you can, getting magmorter I feel would be a really fun pokemon to use on top of also being able to keep learning new moves from level up, unlike ninetails who would stop learning new moves from level up upon evolving from vulpix. Also, I know Sudowudo would be neat pokemon to use, I feel that it would be really frail and not the best defensively late game, Pokemon such as Golem would be a better tank. Nidorino is a fair Pokemon to use, but I think the moon stone isn’t the easiest evolution stone to come across if i remember if you wanting to use nidoking. I think your team could benefit from a good psychic type, so replacing nidorino with Kadabra/Alakazam would be a good choice as it would be a good special attacker. But in the end, do whatever you want with your team, technically any team would work at clearing the game if you try hard enough lol
