Right now: the best rip in Battle of Chaos is the Booster Box [1st Ed] (24 packs) at $66.33 against $62.71 of expected pulls — a −20% margin after ~15% selling fees, and a 40% chance it actually pays for itself. Figures refresh every two hours.
Battle of Chaos (February 11, 2022) is a standard Yu-Gi-Oh! core booster: nine cards per pack, one Rare and one foil per pack, 24 packs per 1st Edition box, with five Starlight Rares as the top tier. Its chase list leans heavily on Dark Magician and Blue-Eyes cards, and sealed has settled into modest collector pricing with margins recently modeling negative.
The foil slot carries the EV. Community estimates give it a Super Rare 65% of the time, an Ultra Rare a bit over a quarter, a Secret Rare about 1 in 14 packs and a Starlight 1 in 100. The Dark Magicians Starlight leads, but the plain Ultra Rare Dark Magician is the oddity: an Ultra that outprices most of the set's Starlights.
Two products are listed: 1st Edition loose packs and the 24-pack 1st Edition box. The box is the cheaper route per pack and has recently modeled closer to break-even; the live table below gives the fee-adjusted margin and the odds each product clears its cost. Rates are community estimates, and with five Starlights sharing a 1% slot, the box's result depends on which foils turn up.
