Battles of Legend: Monstrous Revenge (BLMR, June 23, 2023) brought the 25th-anniversary Quarter Century Secret Rare finish to Yu-Gi-Oh!'s all-foil Battles of Legend line. Packs still hold five foils and boxes 24 packs, but the top tier is now a 25-card Quarter Century Secret list instead of Starlights, which gives the set a deeper chase than most of its siblings.
The model gives each pack four Ultra Rares plus a Secret Rare slot that upgrades to a Quarter Century Secret about once per three boxes. The Bystial Lubellion and Sky Striker Mobilize - Engage! head that list, with Dark Armed Dragon, Super Polymerization, Terraforming and Welcome Labrynth behind them. Every one of the 25 QCSRs shares the same upgrade odds, so any single card is a long shot.
Loose packs and the 24-pack box are tracked. With low sealed prices relative to the reprint list, the box is the straightforward way to buy 24 Secret slots at once. Konami publishes no ratios, and the Quarter Century upgrade rate is a provisional community estimate. Check the live table below for each product's fee-adjusted margin and odds of clearing its cost.
