I'll tackle this in steps ā first let me gather the card IDs and meta report simultaneously, then drill into the custom deck analysis.
Good, I have the card IDs. Now let me find all entries with exactly 4 Sage of the Skies AND at least 10 Plains in the mainboard+sideboard combined (total across the deck). Let me run the query to identify qualifying entries and their overall winrate, then their matchup winrates vs each of the top 10 archetypes.
The result column values are all zero, which suggests the result is stored differently. Let me check the actual result values in the matches table.
Here's what the data shows for @McFishyMTG.
Overall winrate: Decks running exactly 4 Sage of the Skies and at least 10 Plains total posted a 21-20 record across 6 entries in the last month in Standard, good for a 51.2% winrate (excluding draws). The sample is small, so treat these figures as directional rather than definitive.
Matchup breakdown vs the top 10 meta archetypes (7 of the 10 were encountered):
The deck looks strong against aggressive/landfall strategies but gets crushed by controlling blue-based decks (Jeskai Control and Dimir Excruciator). Again, with only 6 qualifying entries total, these matchup numbers are extremely low-sample and should be read with caution.
