I'll analyze the performance of Izzet Lessons with and without Monument to Endurance in Standard over the last month.
Now let me query the database to compare performance with and without Monument to Endurance:
Based on the tournament data from the last 30 days, I found no Izzet Lessons/Izzet Midrange decks playing Monument to Endurance in Standard. All 10 recorded entries ran without Monument to Endurance and achieved a 57.8% winrate (26-19 record across matches).
This indicates that Monument to Endurance is not being adopted in competitive Izzet Lessons lists. The archetype focuses on discard synergies with cards like Stock Up and Ral, Crackling Wit, but players are not including Monument in their builds. Without any decks running Monument to Endurance in the sample, I cannot provide a direct performance comparison.
The archetype's current configuration without Monument appears to be performing solidly above 55% winrate, suggesting players have found success with other card choices in that slot.
