I'll analyze Izzet Lessons performance with and without Monument to Endurance in Standard over the last month.
Let me search for the correct archetype name in Standard:
I see "izzet midrange" in the data. Let me check if that's the archetype you're referring to, and then analyze Monument to Endurance usage:
I don't see Monument to Endurance in the mainboard cards. Let me check if it's being played and then compare performance with and without it:
The data shows that none of the 10 Izzet Midrange entries in the last month played Monument to Endurance. Let me verify this by checking all Standard decks to see if any deck is playing Monument:
I don't have sufficient tournament data to answer this question. Monument to Endurance was not played in any Standard deck over the last month (November 12 - December 12, 2025), including in any of the 10 Izzet Midrange entries recorded. Without any instances of the card being played, I cannot compare performance with versus without it.
If you're considering testing Monument to Endurance in Izzet Midrange (or "Izzet Lessons" as you called it), the current tournament data shows zero adoption, suggesting the card is not currently part of competitive Standard lists for this archetype.
