Right now: the best rip in Paramount War (OP02) is the Booster Box (24 packs) at $579.17 against $53.88 of expected pulls — a −92% margin after ~15% selling fees, and a 0% chance it actually pays for itself. Figures refresh every two hours.
Paramount War (OP02) released March 10, 2023, themed on the Marineford war and the Whitebeard era of the story. It's a pre-Treasure-Rare set: 12-card packs where the hit slot delivers a Super Rare about 55% of the time, a Leader about 25%, and a Secret Rare roughly 6% — call it one or two SECs in a typical 24-pack box.
As the game's second-ever set, OP02 sealed has aged into a collectible in its own right, and that's what wrecks the rip math. The box price reflects scarcity and nostalgia; the cards inside reflect an early chase pool at today's singles prices. The gap between the two is wide and structural — new print runs won't touch early-wave boxes, and the singles market has long since settled. The live EV below will confirm it, but this is a hold-or-buy-singles set, not a rip.
