Right now: the best rip in Royal Blood (OP10) is the Booster Pack at $9.47 against $3.71 of expected pulls — a −67% margin after ~15% selling fees, and a 2% chance it actually pays for itself. Figures refresh every two hours.
Royal Blood (OP10) released March 21, 2025, as the tenth main One Piece booster, and by this point the formula is set in stone: 12 cards per pack, 24 packs per box, one rare slot and one hit slot. Community estimates put the hit slot at roughly 55% Super Rare, 25% Leader, 5% Secret Rare and 1% Treasure Rare — so a typical box yields about one SEC, and a TR shows up around once every four boxes.
That concentration is what decides the math. The Rares and SRs filling most packs are worth very little on the singles market, so nearly all of Royal Blood's EV rides on the SEC pool and the Treasure Rare. Sealed, meanwhile, is priced for the fun of chasing them. The result — visible in the live table below — is a persistent gap between what a pack costs and what it returns on average. If you want specific cards from OP10, singles remain the boring, correct play.
