That’s a strawman. I believe the best players in the game combine both netdecking and homebrewing; they never do only 1 or the other; they are always sharping their skill on both. They are always on the lookout for the best decks currently played; they are always looking for advice and their own insight on what new cards to use to become better than others; it’s inevitable that they know how to build as well because it’s an inevitable intuition if you understand deeply the …cards.
