yeah this is why most people who stream mtg arena and eternal do drafts a lot of the time, or are the kinds of people who figure out those top tier decks by just throwing shit at a wall to see if it works
Which is basically Draft As A Formal Norm. You buy premade random decks - 10 cards from each of 3 of the game's 10 'colors'. Every deck has a unique back, so in standard play, there's no mixing decks. You pick the deck you have that best suits the event you're in (and even register it by name.)
I have won a draft and a constructed event tho
