It seems there are no entries for Izzet Lessons in the Standard format within the specified date range. This could be due to the archetype not being widely played or the data not being available in the database for that period.
To provide a more accurate analysis, we would need data on Izzet Lessons' performance, including whether or not it plays Monument to Endurance. However, with the current data, we cannot determine the impact of Monument to Endurance on Izzet Lessons' performance.
