I strongly dissagree with that. Decks are not autobuild. Yes a big part will be decided by the archetype, but the usage of engines and techs clearly makes a deck different. On top of that you have to read the meta and prepare accordingly. What decks will come up, how will I counter them and how will they counter me. Side deck, main deck and extra deck choices are crucial and does require a good read of the meta.
Now turn one advantage is huge but player 2 gets card advantage. Which considering what we are willing to sacrifice for pot of desires is huge. Also some decks have poorer turn 1 plays then turn 2 plays.
For me the long turns are equally interesting: what do they play, how do I get past it, what do they have in the hand, what do I negate/destroy and what might come on the field after that? To me the game became an interactive puzzle which I have to solve. Also making reads/predictions is still important even though the game became a lot more lineair. Predicting a quaking mirror force against the chaos max might be the difference between victory and loss. After a while the plays become more easier but that is experience not some hand guide.
