The "Azorius Tempo" overview matched Standard, not Legacy. Let me look up the correct Legacy archetype and search for "The Riddler" via its Universes Within name, and pull card data simultaneously.
I can see "Azorius Midrange" in the Legacy meta report. That's likely the closest match. Let me look it up and also search for Phelia and Stoneforge presence in that archetype.
The key cards confirm this is indeed the Legacy Azorius Midrange archetype (Force of Will, Brainstorm, Tundra, Swords to Plowshares). Now let me pull its archetype cards and run the Stoneforge split query simultaneously.
The archetype_id matched Pauper, not Legacy. Let me query the Legacy archetype directly from the database and run the Stoneforge split.
Now I have the correct Legacy archetype IDs. The "Azorius Midrange" (id: 36620012) is the most likely match for the tempo deck with Phelia and Quantum Riddler. Let me now pull the card data and run the Stoneforge split for that specific Legacy archetype.
Good, got the Riddler card ID. Now let me run the full Stoneforge split for the Legacy Azorius Midrange archetype.
Interesting - Stoneforge Mystic doesn't appear in any of the entries. Let me check the sideboard and verify Stoneforge presence more broadly.
I now have a complete picture. Here's the full breakdown for @JurgenKowalsky:
Hey @JurgenKowalsky, here's what the data shows for Legacy Azorius Midrange (the Phelia + Quantum Riddler tempo build) over the last two months (Apr 15 - Jun 15, 2026), across 70 total entries in 44 tournaments.
STONEFORGE MYSTIC: NOT PRESENT IN THIS ARCHETYPE
Stoneforge Mystic does not appear in a single mainboard or sideboard slot across all 70 entries in the dataset. This version of Azorius is firmly a tempo/Phelia shell, not a Stoneblade shell. If you're comparing to Azorius Stoneblade (a separate archetype in the database), that would be a different deck entirely.
PHELIA + QUANTUM RIDDLER BUILD (54 of 70 entries, 77.1% of the field):
Both Phelia and Quantum Riddler show up together as a package in 54 entries, each at 77.1% presence and averaging ~4 copies each. That combined tempo engine is clearly the defining characteristic of the deck. Those 54 entries post a 108-101 record (51.67% winrate, excluding draws). The 16 entries running neither card - likely older or more transitional shells - went 32-31 (50.79%). The gap is modest but directionally favors the Phelia/Riddler build.
The deck's overall record across all 70 entries is 140-132 with 9 draws (51.47% winrate), putting it squarely in "viable but not dominant" territory - 12th in Legacy meta share at 2.77% of matches. The core shell is very consistent: Force of Will, Brainstorm, Swords to Plowshares, and Ponder all run at 100%, with Wasteland (92.9%), Tamiyo (90%), Daze (81.4%), and Stifle (74.3%) rounding out the tempo package.
