I need to first look up the Dimir Tempo archetype to understand what we're working with, and also get recent meta context for Legacy.
Good, now I need to identify the two builds of Dimir Tempo — specifically the "Moonshadow" build vs. the other build. Let me search for what differentiates them by looking at the cards in the archetype, and then query the database to split entries by whether they contain Moonshadow-related cards.
I can see Moonshadow appears in ~30% of Dimir Tempo decks. Now let me query the database directly to split entries by those with vs. without Moonshadow and compare their win rates.
The match results are returning zeros for W/L/D — likely a schema issue with how result is stored. Let me check the actual values in the matches table and fix the query.
Result values are WIN, LOSS, DRAW. Let me re-run the winrate split with corrected values.
Clear results. Let me grab sources to cite.
Here's the breakdown:
Short answer: No — the Moonshadow build actually underperforms vs. the field.
| Build | Entries | Matches | Wins | Losses | Winrate |
|---|---|---|---|---|---|
| 🌑 Moonshadow | 49 | 194 | 95 | 96 | 49.74% |
| ⚔️ Non-Moonshadow | 116 | 396 | 206 | 180 | 53.37% |
(Mirror matches excluded from both)
The Non-Moonshadow build has a +3.63% winrate advantage vs. the full meta over the last 60 days. Moonshadow appears in ~30% of Dimir Tempo lists (usually as a 4-of when included), but it's currently dragging the build below the 50% threshold while the more conventional shell sits comfortably at 53%.
Worth noting that the sample for the Moonshadow build is smaller (49 entries vs. 116), so there's some variance involved — but the gap is notable enough to be meaningful.
