Hall Eevee

Q: What is this challenge?
A: I'm trying to beat the Battle Hall with "every" Pokemon in the game, currently working on Eevee.

Q: Why the Battle Hall specifically?
A: The Battle Hall is unique from any other facility in the Battle Frontier, as only one Pokemon can be used, meaning the Battles are in 1V1 format, which is perfect for this challenge, as each Pokemon will have to win on its own merit.

Q: What is required to beat the Battle Hall?
A: To win, you have to clear 170 Battles in a row, 10 Battles for each Pokemon Type, divided into 17 Rounds.

Q: Why are the opponents using weak Pokemon?
A: Each Pokemon Type has an individual ranking system which determines what Pokemon can show up as your opponents. Lower Ranks have weak Pokemon as opponents. Higher Ranks have strong Pokemon as opponents.

Q: Can you explain Ranks in more detail?

Q: Why is your Pokemon Level 30? Why are the opponents lower Level?
A: I'm Level 30 because it's the lowest Level Eevee can be used at, and since I'm playing on Console, I want to spend the least amount of time possible grinding Levels. The opponents are lower Level, because there's Level Scaling throughout the challenge. Early Rounds have low Level Pokemon. Late Rounds have high Level Pokemon.

Q: Is there a Boss Battle in the Battle Hall? What is a SKIP?
A: Yes, Hall Matron Argenta, in Battles 50 & 170. Battle 50 will be against a Pokemon from the same BST Group as Eevee. Battle 170 will be against a 500+ BST Pokemon. Each Boss Battle replaces a regular Battle, and that's what a SKIP is. E.G. If I try to fight Rank 10 of "X" Type in Battle 50, it gets replaced by the Boss Battle, and I only have to do 9 Ranks of "X" Type, which is useful for avoiding scary Pokemon.

Q: Why are you using the Rest function at random intervals?
A: Rest, meaning the Save & Quit option, is useful for improving my odds of avoiding problem matchups. This video by MagpieLabs does a good job of explaining: https://www.youtube.com/watch?v=xT4ltLquMkM
TL;DR: The way opponents are generated in the Battle Hall isn't truly random, and using the Rest function can "fix" it. I'm considering banning this exploit for myself, but for now I'm still using it.

Q: Be honest. Can you really win with Eevee? How?
A: Yes! While I'm only allowed to use Eevee, nothing stops me from using a different Eevee for each round. What this means in practice, is that if necessary, I can train up 17 different versions of the same Pokemon, tailor-made to counter each of the 17 different Pokemon Types.

Q: What Sets are you using for each Round? Why?
A: You can find my Sets below. I don't feel like writing long-winded explanations for every different Pokemon in each of my Pastebins, but feel free to ask me for my reasoning behind the Sets and I'll do my best to explain. Keep in mind, this is just what I came up with, doesn't necessarily mean it's optimal.
