Ancient Trial Rally Challenge is the thirtieth mission in Mario Tennis Aces, taking place in the Green Trial. It is only playable once the player updates to version 2.0.0.
In the match, Mario must keep rallying the ball to a transparent clone of himself. Each individual rally is worth one point. Unlike all other Rally Challenge missions, Mario can score as many points as possible, although he must score at least 400 to win. Mario scores ten bonus points for the tenth consecutive rally, twenty points for the twentieth consecutive rally, and thirty points for every ten subsequent consecutive rallies. The mission ends in a failure if Mario misses a ball three times.
- "Demonstrate your skill by scoring more than 400."
