Please rate my rain team! :D

Question

Bred these guys on a road trip and they've been seeing success in casual and even ranked battles! Planning on using them for Same Double Beat, but are there any improvements y'all would suggest?
Edit: sorry if I didn't make it apparent, this team is for in-game casual & ranked battles

What format?

---

In game ranked/casual battles and for that same double beat tourney thing

---

Sorry but what is the Same Double Beat tourney?

---

Upcoming online competition in Sword & Shield, it's doubles with duplicate Pokémon & items allowed (though my team doesn't make use of that) and special Pokémon are banned

---

Why use Jolteon? Other than thunder it doesnt have anything like swift swim or lightning rod tointeract with rain or redirect electric attacks. Something like Raichu would be better with fake out support and lightning rod to redirect electric attacs away from the other pokemon.
