Let me pull the data needed to answer this — first I'll look up both cards and the Goryo's archetype overview simultaneously.
Got the archetype ID. Now let me query the database directly to compare win rates with vs. without Quantum Riddler.
Here's the breakdown for Goryo Reanimator over the last ~2 months:
Goryo's Vengeance — Quantum Riddler Split
| Entries | W | L | D | WR% | |
|---|---|---|---|---|---|
| With Quantum Riddler | 153 | 280 | 282 | 8 | 49.8% |
| Without Quantum Riddler | 3 | 6 | 10 | 2 | 37.5% |
Verdict: With Quantum Riddler is better — but with a major caveat.
Bottom line: Run Quantum Riddler. The field has spoken — nearly every competitive Goryo pilot includes it, and the data supports that choice.
