I'll analyze Izzet Lessons performance with and without Monument to Endurance in Standard over the last month.
Let me check what Standard archetypes are available and look for Izzet-based decks:
I see "Izzet Midrange" in the meta. Let me check if that's the archetype you're referring to and analyze Monument to Endurance usage:
I don't see Monument to Endurance in the main deck cards. Let me query the database directly to analyze performance with and without Monument to Endurance:
Monument to Endurance does not appear in any Izzet Midrange lists over the last month. All 10 tournament entries ran without it, posting a 57.78% winrate (26-19 excluding draws). The archetype focuses on discard-synergy cards like Stock Up, Stormchaser's Talent, and Quantum Riddler, but Monument to Endurance is not part of the established build.
Without any data showing the card in Izzet lists, I cannot meaningfully compare performance with versus without Monument to Endurance. The card may not synergize with the deck's game plan as well as the current card choices, or it simply hasn't been tested in the archetype during this period.
