I'll analyze the UB frog deck's performance in Modern based on Quantum Riddler count and identify which matchups are most affected. Let me start by gathering the relevant data.
Now let me query the database to analyze the UB/WUBR frog deck's performance based on Quantum Riddler count:
Let me check what entries we have for this archetype first:
Let me try a broader search for UB frog variants and check what archetypes exist:
The "UB frog" likely refers to Dimir Frog. Let me analyze that archetype's performance with Quantum Riddler:
Now let me analyze matchup differences. I'll look at the most common matchups for Dimir Frog and compare performance with and without Quantum Riddler:
I'm seeing an issue with the match results data. Let me check the match results structure:
Now let me fix the query with the correct result values:
Let me check if there are enough matchups with Riddler to make meaningful comparisons by lowering the threshold:
Now let me get sources for this analysis:
Based on my analysis of Dimir Frog's tournament performance with Quantum Riddler, the overall winrate difference is minimal. Decks without Quantum Riddler post a 48.3% winrate (134 entries, 276-296 record), while builds with 1+ Riddlers achieve exactly 50.0% (5 entries, 16-16 combined record). The sample size for Riddler builds is extremely small.
However, the matchup analysis reveals some interesting patterns where Riddler appears to help. Against Amulet Titan, the winrate jumps from 47.2% to 66.7% with Riddler (3 matches). Against Broodscale, it improves from 47.4% to 66.7% with Riddler (3 matches). Against Boros Energy, Riddler versions show 50.0% versus 46.3% without (6 matches with Riddler). Conversely, against Goryo Reanimator, the Riddler version performed worse at 33.3% versus 56.0% without (3 matches).
The extremely limited sample size for Riddler builds makes these results unreliable for definitive conclusions. Most competitive Dimir Frog builds are currently running 0 copies, suggesting the card hasn't found consistent adoption in the archetype.
