I started around 2400 or 2500 during the beginning of fossil cup but this team put me to leaderboard (currently sitting at 3200 as of right now). And I also got shiny libre pikachu thanks to this team!

The team is Lanturn, Ludicolo, and Ferrothorn.

The reason I do this is I love ABB team and lanturn literally beats all water and playable against most steel, so putting him as a lead literally put you in a high chance to win lead in most cases. There aren't a lot of grasses in the meta besides Ferrthorn, Katarina, and Ludicolo, but Katarina is almost not obtainable and I have two answers for Ludi.

It does get countered by Ferrothorn hard, but in my ELO not a lot of people start off with it. I typically safe swap to my own Ferrothorn and if they switch to a poliwrath or counter user, then it's pretty much good game, but other than that, this team is just broken because if that person has no answer to Ferrothorn and he would need to stay with his. And with Lanturn and Ludicolo left, I basically sweep almost anything if I don't mess up.
