Right now: the best rip in Duelist's Advance is the Booster Box [1st Ed] (24 packs) at $33.99 against $63.44 of expected pulls — a +59% margin after ~15% selling fees, and a 86% chance it actually pays for itself. Figures refresh every two hours.
Duelist's Advance (July 4, 2025) marks a structural break: the first core booster after Quarter Century Secret Rares were retired. The top parallel tier is now an expanded 25-card Starlight Rare pool — similar 1-in-100-ish odds at the top slot by community estimates, but a different rarity carrying the ceiling. Pack construction is otherwise unchanged: nine cards, one guaranteed foil, 24 packs per box.
A caveat on our numbers: with Starlights spread across a much bigger pool than the rarity historically used, our slot model prices that tier conservatively, so the EV shown below may understate a genuinely hot box. The rest is standard core-booster reality — Secret Rares around 1 in 14 packs, and eight near-worthless cards surrounding the foil slot.
The set also sells as a sleeved single pack alongside regular packs and boxes, and per-pack cost differs meaningfully across the three — margin follows the entry price. The live tables below compare all of them at current prices.
