I don't recall saying Magneboar was the "best developing deck."
My post wasn't just a response to yours, but also a general response to Vaporeon and anyone else who thinks I am for some reason arguing that "META IS THE SOURCE OF ALL GLORY FOREVER AND EVER AMEN."" That is a bad mentality to have too, and I don't want anyone to think I have it. I strive to be a "total" player, hence the reference to me not being restricted in my approaches to any facet of this game.
Never said you thought so. "If" you think MagneBoar is one of the best developing decks (which I and most of the community do), and decided to play it in a matchup of you and Vaporeon, you'd represent meta in this instance of Vaporeon vs. BFH. I don't think that you think Meta is the source of all glory, but in this isolated instance, it seems to me that you would take a tested deck with synergy (like LuxChomp the past format) while Vaporeon would take an unproven rogue deck of two random pokemon.
