I'll analyze the performance of Izzet Cauldron decks without Marauding Mako in the last 15 days. Let me start by identifying the relevant format and getting the necessary IDs.
Now I'll query the database to find Izzet Cauldron tournament entries from the last 15 days that do NOT contain Marauding Mako, and analyze their performance:
Let me also check the overall performance statistics for these non-Mako Izzet Cauldron builds:
In the last 15 days, Izzet Cauldron decks without Marauding Mako have shown exceptional performance with only 5 recorded entries but impressive results. The top performance came from Mizl1zzie who won a Standard Challenge 32 on September 27th with an 8-1 record (88.9% winrate). Other notable finishes include Jiliac's 6th place finish with a 5-2 record (71.4% winrate) and Falcon's 12th place with a 3-1-1 record (75.0% winrate).
Overall, these non-Mako Izzet Cauldron builds achieved a 71.4% winrate across 28 matches (20-8-2 record), which is significantly higher than the archetype's general 56.9% winrate. The sample included 1 tournament win and 2 top-8 finishes out of 5 entries, suggesting that builds without Marauding Mako may actually be performing better than the stock versions.
However, the sample size is quite small with only 5 entries recorded in the last 15 days, so these results should be interpreted cautiously as they may not represent the archetype's true performance without the card.
