Right now: the best rip in Carrying On His Will (OP13) is the Booster Pack at $11.53 against $2.69 of expected pulls — a −80% margin after ~15% selling fees. Figures refresh every two hours.
Carrying On His Will (OP13) released November 7, 2025, as the game's third-anniversary set, and Bandai celebrated by super-sizing the chase: an 18-card Secret Rare pool, the largest of any main booster. The hit slot still lands a SEC about 1 in 20 packs by community estimates, but with 18 candidates, any particular card works out to roughly 1 in 360 packs if evenly weighted — call it 15 boxes for one specific pull.
That dilution defines the set. Anniversary hype kept sealed prices firm while the odds of hitting the exact SEC you want got dramatically longer, and the lone Treasure Rare at about 1 in 100 packs can't carry the difference. The result is a set that's great fun to open and rough on the wallet in expectation. The live table below shows how big the gap is right now; for specific anniversary Secret Rares, the singles market is the only sane route.
