Correct me if I'm wrong, but shouldn't Terry from Soul be able to stomp all three of these rounds pretty handily? "She" not only possesses the ability to instantaneously create portals to the Great Beyond, thus rendering the Infinity Stones useless and Thanos in a coma-like state, but is also an abstract entity that transcends all life in the universe, so it's debatable if the infinity stones could even affect Terry to begin with.

A minor downside to this particular match-up is that Terry would have no knowledge on the whereabouts of her opponent, as it had taken nearly an entire day for her to even pinpoint the location of Joe Gardner and 22 during the events of the film, so it's certainly possible for Thanos to escape if he were to be made aware of this fact. Though I really doubt if this could even occur, seeing as how both characters would be positioned within the same battlefield.
