An MTG limited player named Ryan Saxe created an AI that drafts and builds deck to a highly successfully degree:
https://github.com/RyanSaxe/mtg
He was able to reach Mythic, the highest ranking tier on Magic Arena. Of course this is a different problem to actually playing the game (and probably significantly easier). That being said, this is one guy doing it as a side project with restricted resources.
I imagine that MTG could played quite successfully by an AI if someone where to dedicate the resources. Imo much of the difficulty is in laying the groundwork. Large amounts of data don't exist publicly and laying the framework for a bot to play itself would be quite difficult (and then the computation costs would be extremely expensive).
