I'll analyze the winrate of Izzet Cauldron in Standard with and without Marauding Mako. Let me start by getting the current Standard format information and finding the relevant cards and archetype.
Now let me query the database to analyze the winrate of Izzet Cauldron decks with and without Marauding Mako over the recent period.
Let me also get recent tournament sources for citation:
Based on my analysis of recent Standard tournament data, Izzet Cauldron shows virtually identical winrates with and without Marauding Mako. Decks running Marauding Mako achieved a 56.7% winrate across 865 entries, while decks without the card posted a 57.3% winrate across 35 entries. The difference of 0.6 percentage points is negligible and likely within statistical noise.
The overwhelming majority of Izzet Cauldron builds (96.1% of entries) include Marauding Mako in their main deck, suggesting it has become a standard inclusion in the archetype. However, the small sample of decks without Mako performing equally well indicates that the card, while popular, may not be essential to the deck's core strategy.
This data suggests that Marauding Mako fits well into the Izzet Cauldron gameplan but isn't necessarily improving the deck's overall win percentage. The card likely provides value through synergy with the deck's discard effects and cycling mechanics rather than raw power level improvements.
