[DISCUSSION] BATTLE TREE

[Dimmsdale]

I've been working on getting a 50 win streak to face the battle legends in both Super Singles and Super Doubles and I've been having trouble for quite a while.
What teams have you guys successfully used to get 50 win streaks in the battle tree in either format?
I'm currently working on an Alolan Sandslash/Alolan Ninetales/Tapu Koko/Garchomp/Arcanine/Celesteela or Snorlax, leading with the Aurora Veil on HA Ninetales and a HA Sandslash
My best record in Super Doubles so far is a 44 win streak, what is yours?

[Arctero]

I got a 58 win streak in super doubles with torkoal, tangrowth, golisopod and minior.
