Hi! The reason why there’s a rule regarding moveset threads is primarily because of reoccurring issues such as quality and organization/spam. To keep the site in tip-top shape, it’s much more easier to have one thread per final evolved form for easier access, easier organization, and more quality-control.
For in-game teams, the truth is… literally anything can work for in-game! No matter how bad a set may be, it’ll probably work in-game. If you really want a good set, you can check the competitive threads and modify for your liking. Look at commonly repeated attacking moves to get a good feel for what’s good on that Pokémon, and check the site to see if it’s available in the gen you’re playing. It really depends what you want and what will work for your team. The reason why we don’t have a thread for every generation is because… that’s a lot of new pages for the same Pokemon! A bit excessive, don’t you think? This falls into the organization aspect I mentioned earlier.
You can also ask in chat or on walls of other members for what they think may be useful for in-game. There’s plenty of people with lots of experience who’ll be willing to help.
I hope this helps! If you need further clarification, let me know. I hope you have a better understanding as to why it’s a rule now :)
P.S. Surf and False Swipe are pretty good in-game for Linoone… just saying ;)
