May not be a simple question, but how do you build sun in LC? It seems super fun but I suck at teambuilding in LC. If there are any videos discussing the topic. Please link them!
With how hyper-specialised sun is, it's kind of hard to "build" per se, as the current sun teams used in the meta right now are pretty optimised, if that makes sense. That being said if you wanna try, If I had to rank the components of a sun team in order of necessity it would look something like
S-Tier - Vulpix, Scarf Charmander
A-Tier - Diglett, Defog Timburr, Ponyta
B-Tier - Larvesta, Natu, Magby, Other Random Stuff.
Here are some sun teams you can use as inspiration:

- Standard Sun

- Lily Sun

- Trubbish Sun (this one might be bad)
Finally, here is a replay of the second team being used effectively in a match between top players in a Little Cup tournament

I hope this helps!
