PLEASE DO NOT MAKE FUN OF OTHER USERS FOR THEIR ELO. I STRONGLY RECOMMEND POSTING IT YOURSELF FOR GOOD FAITH, EVEN IF IT IS LOW LIKE ME

Here is a list of things I need help with.
Gen 3 OU:
What is THE objectively best play vs the 5 common leads on turn 1 when playing this skarm lead big 5 tss? Surely there's an on paper play that's optimal.
Example team: https://pokepast.es/aec34e0b8d519dd9
Gen 5 OU:
Does anyone have any agilipass teams based around sweeping with LO sand force excadrill or SD/Bulkup breloom? It actually seems like a not so bad cheese.
What about omastar teams to fish vs rain?
Gen 7 OU:
I need a spread for defensive pelipper on rain. I think smogon's is suboptimal/outdated?
Gen 8 OU:
I need a good team with urshifu+magnezone
VGC:
Can someone explain the ludicolo spreads here on pikalytics? Not familiar with using him outside of z sets in gen 7.

Feel free to ask for and give advice, post or request teams, discuss the meta, discuss smogon or vgc, whatever. It makes me mad that competitive threads is just people insulting instead of real discussions.
