Hello,
I will submit your suggestion to fix Matsuri Challenge Arena along to the developers! A few points of clarification, however:

- Please ensure that you do not go over the 30 second window. Once you do so, you will be matched with anyone, regardless of their record!

- Matsuri Challenge Arena does not actually guarantee matching opponents of similar power, and power is not a factor for this event! Rather, it will attempt to match you to opponents with similar win/loss records. This may mean that an opponent that is vastly stronger than you that has had an unlucky break could be your opponent if they have a similar win/loss record to yours! This design is to help and protect people that are on unlucky streaks by giving them easier opponents. Sometimes a player will get lucky and find a player that is doing well and "punching above their weight class" and sometimes a player will be unlucky and find a strong opponent that has had a streak of bad luck.

Thank you for participating in Matsuri Challenge Arena, and best of luck moving forward!
