Let me gather the data needed — I'll pull the Izzet Prowess archetype overview and recent card breakdown simultaneously.
Interesting — the overview returned Izzet Prowess in Standard, not Modern. Let me check if there's a Modern version, and simultaneously pull the card-level win percentage data for both the main and sideboard.
No Izzet Prowess data in Modern over the last 60 days. Let me check what's in the Modern meta and whether Izzet Prowess exists under a different name, and also look at the Standard version's card win rates since that's where the data lives.
I can see "Prowess" exists in Modern (not "Izzet Prowess"). Let me now pull the Modern Prowess card data and run a per-card win rate query on the Standard Izzet Prowess since that's where the robust data is.
Now let me run the same per-card win rate query for the Modern Prowess archetype:
Here's a heads-up before diving in: there is no "Izzet Prowess" archetype tracked in Modern — the closest equivalent is simply called "Prowess" in the database, and it's one of the most-played archetypes in the format (~10.5% meta share). Here's what the per-card win rate data says about optimal construction:
(Last 60 days | 1,016 decks | Overall WR: 49.4%)
These are in virtually every list and form the non-negotiable backbone:
| Card | Presence | WR% |
|---|---|---|
| Mishra's Bauble | 100% | 49.44% |
| Cori-Steel Cutter | 100% | 49.44% |
| Lava Dart | 100% | 49.44% |
| Lightning Bolt | 100% | 49.44% |
| Monastery Swiftspear | 99.9% | 49.43% |
| Dragon's Rage Channeler | 99.6% | 49.44% |
| Preordain | 99.5% | 49.46% |
| Thundering Falls | 98.6% | 49.54% |
| Slickshot Show-Off | 93.8% | 49.16% |
| Expressive Iteration | 91.5% | 49.15% |
| Mutagenic Growth | 91.2% | 48.94% |
These flex slots post above-average WR despite lower inclusion rates, suggesting they correlate with better-tuned lists:
| Card | Presence | WR% | Notes |
|---|---|---|---|
| Assault Strobe | 12.8% | 52.98% | Highest WR in the archetype |
| Unholy Heat | 35.4% | 51.96% | Delirium removal upgrade |
| Monstrous Rage | 17.0% | 52.11% | Pump + trample |
| Stormchaser's Talent | 25.8% | 50.34% | Sustained card advantage |
| Card | Presence | WR% |
|---|---|---|
| Violent Urge | 68.7% | 48.78% |
| Flashback | 10.9% | 47.62% |
| Mutagenic Growth | 91.2% | 48.94% |
Per-card win rate reflects the performance of decks that included those cards, not isolated card power. Cards like Assault Strobe (52.98%) show up in lists that are already tuned to close out games fast — so the WR signal is partly a proxy for deck-building philosophy, not just the card itself.
The data suggests leaning into Assault Strobe + Monstrous Rage as your flex 8–12 slots over Violent Urge if you want the highest-performing builds.
