Many people have different definitions of rogue decks. I consider a deck is a rogue deck if it does fairly well against a couple (or more) Tier 2-3 decks, and isn't played that much competitively. However as I said, different people will give you different definitions.
Tier 1 are the best decks atm. They do well wherever they go, and often these win Worlds if there are no Tier 0 decks (which Idt I've seen ever in Pokémon). Tier 2 are decks that are very good too, but one flaw or another keeps them from being Tier 1. It can be their speed, their consistency, etc. These can be as good as Tier 1 though, you just gotta know your deck.
Tier 3 are rest of the decks, and iirc rogues go here. They are often decks that do well in tournaments from time to time, but are too inconsistent/slow/rare to make any sort of impact in the game.
I mentioned Tier 0 earlier, and I'll explain what it is now. Tier 0 decks are decks that are so good that the format is 'play this or get rekt.' As I also said earlier, I don't think I've ever seen this in Pokémon. These have like 99.99999999% chances of winning Worlds, unless they somehow get bad hands or their opp gets lucky.
Hope this helped!
