This post is an unnecessary rant lashing out at off-metaers for some unknown reason. I don’t really understand why your complaining, other than probably losing to an off-metaer and getting bm’d for being worse than them cuz you were using some meta deck.
Regardless, to say that deck building is meaningless is absurd. Building alternate decks isn’t about finding an “easier” way to play, it’s about finding an advantage people haven’t found yet. Pros build decks with small variations to explore advantages. Homebrewers are simply looking for larger advantages. If the current meta decks aren’t even optimized yet, what’s to say there aren’t any better decks out there? It’s foolish to assume all decks should just be netdecks, especially when there are over 300 cards in rotation. If you want to play a game where deck building truly doesn’t matter, play a 52 card playing card game, or UNO.
