I think you’re being too harsh here. The author didn’t come close to claiming that MtG drafting was solved; instead the claim is that they were able to train a fairly straightforward model to perform relatively well — within the metric of “as hand-judged by a proficient player” — to draft cards.

There is a vast amount of interesting space (both as AImresearch and as a fun toy) between “fully groks the current and predicatable near-future meta on a professional level” and “drafts playable decks”. As I read it, the OP is saying “Hey, I built something surprisingly simple that can draft playable decks. When I compare it to an available corpus of draft data from random human players, I think it does as well or better.” On the other hand, I don’t see anything like “I built AlphaGo for Magic drafts.”
