I can understand where that complain comes from: in the past, Expanded has had some degenerate combos, and its not fun to play when, on your first turn of the game, your opponent has already set up a Vileplume (Ancient Origins) preventing you from playing Item cards, or used some combination of cards to make you discard all your hand
Whether youre unlocking the high-impact effects from Tomb of Annihilation or Dungeon of the Mad Mage, or switching on bombs like Nadaar, getting 4-7 venture triggers is going to be a make-or-break for dungeon-focused Draft decks
I would compare it to how adventures allow you to potentially use both halves of the same card, except Rooms allow you to play their halves in either order
You wont get to flip all their artifacts and enchantments as you do with Cyclonic Rift
Heck, thats what the name Unlimited was originally supposed to meanthe black-bordered set would have a limited print run, while the white-bordered set would have an unlimited print run
However, if a card states you can have as many in your deck as you like, you can have multiple of those cards
