Methodology and sources
Formula: EV_pack = Σ (per-pack probability of each rarity × average EUR price of that rarity's cards in the set). The breakdown above lists exactly those terms.
Prices: latest Cardmarket EUR quote per card (230 of 230 cards priced). Within each rarity we use the plain mean of every card — chase cards included. A price is only dropped when it looks like a data error: more than 10× the rarity's median AND more than 3× the next-highest price. Bulk cards are NOT excluded — they are part of the real expectation.
Pull rates: community estimates (documented mass pack openings), never official — The Pokémon Company does not publish pull rates. Within a tier (e.g. Galarian Gallery) we assume uniform probability per card. Reverse holos are valued at the regular card's price. Rows marked * use the era baseline rate because nobody has measured that set.
EV is a long-run average: any single pack will usually return much less (the norm) or occasionally much more (the hit). This is not investment advice.
Community estimates, not official — The Pokémon Company never publishes pull rates. Baseline measured on SV base (8,000+ packs); per-set drift exists (2024 sets Twilight Masquerade→Surging Sparks had Special Illustration Rare closer to 1 in 85-90 packs). ACE SPEC slot applies only from Temporal Forces (sv5) onward; the resolver drops it automatically for sets without ACE SPEC cards. Reverse-holo cards are valued at the regular card's price (reverse variants are not priced separately in our data).

FAQ
Frequently asked questions
- Is it worth opening Obsidian Flames packs?
- On average a pack returns €1.82, 41% of its MSRP (€4.49). As with almost every set, opening packs loses value versus buying singles — you pay for the thrill of the rip.
- How is the expected value (EV) of a pack calculated?
- We multiply each rarity's per-pack probability by the average EUR price (Cardmarket) of that rarity's cards in the set, then sum: EV = Σ P(rarity) × avg price(rarity). A price is only excluded when it looks like a data error (over 10× the rarity's median and 3× the next-highest price); legitimate chase cards count.
- Are these pull rates official?
- No. The Pokémon Company never publishes pull rates. We use community estimates from documented mass openings (TCGplayer Authentication Center, pull-rate aggregators) and cite every source with its date.
- What is a Obsidian Flames box worth on average?
- With 36 packs, the expected contents are worth €65.50. Compare against the real sealed price before ripping.
