Hit a pretty nasty 5-win streak on my way to MB4 as well. In general, whenever I lost with this team it felt like a skill issue.

Team Idea

When I was cooking up ideas for Reg M-B, Raichu-Y was overall the most interesting new Mega to me. Pretty quickly, I landed on the idea of pairing it with Scarf Vivillon to parasleep the opponent to death with accurate Zap Cannons and Sleep Powders. However, I didn't like the idea of being locked into Sleep Powder, so I almost immediately switched Vivillon's item to Sash.

Originally, the team was dual-Mega with Froslass to cover Raichu's bad matchups. I did not end up liking this, as too often I found myself in want of the ice coverage (or weather control) when bringing Raichu, and I generally felt the team wasn't built to support Froslass. Ninetales-A is a mon I used a lot in M-A, so it felt like a pretty natural swap for Froslass. This worked great, and Ninetales ended up becoming a crucial member of the core.

I also saw Wolfe's video pairing Raichu with Gholdengo, so I threw that in there. The main core of the team is Raichu/Vivillon/Ninetales, and then usually Gholdengo. Incineroar and Garchomp are very, very rarely (if ever) brought.

Team Description

99% of the time you will just lead Raichu/Vivillon (with Ninetales/Gold in the back). This duo exerts insane pressure on turn 1. Raichu can almost always fake something out, and then either you're getting Tailwind up or putting something to sleep.

Raichu/Ninetales is also a strong lead, as it gives you immediate Fake Out / Encore pressure. However, be careful leading this against other weather teams, as you do not want to lose the weather war.

I'm not going to go over each mon individually; the sets are generally pretty standard and self-explanatory.

In general, this team relies on positioning and smart play to pull ahead. Opponents have lots of counterplay: switching a Ground-type in on Zap Cannon (or Grass-type on Sleep Powder), redirection, their own speed control, Armor Tail or Queenly Majesty, etc. A good read on the opponent's part (or a bad read on yours) can spell disaster, lol.

Do beware that this team is heavy on special attackers. My most-brought 4 are actually all Special, so this is definitely a weakness opponents can exploit.

Anyways, this was a really fun team to climb with, and I haven't seen anyone else showcase anything particularly similar. Let me know what you think! <3
