Another informal nerd benchmark that AIs had struggled with has been passed: Astra successfully designed a Magic the Gathering deck and then used it to defeat a bot on Arena. (the deck may not be stunning, but it does seem to be original, and it worked) "Can Claude with Computer Use play Magic the Gathering Arena?" Not yet. It does well in card selection & mulligan, and its general strategy is pretty sound, but it sometimes did the mana math wrong and so fails in the end (this ends with it trying to play a card when tapped out)
