Steam Siege

Card power is a printed-numbers heuristic for Pokémon cards inside one set. Score = HP + the sum of attack damage numbers + 15 if the card lists an Ability, Pokémon Power, Poké-Body, or Ancient Trait. The first integer in a damage string is used, so 30× and 30+ both count as 30. A status attack with no number counts as 0. The +15 is only a presence bonus so abilities are not invisible — it is not a rating of the ability text. Trainer and Energy cards are excluded because they have no HP or attack damage. Ties break by higher HP, then collector number.

Each card keeps the rarity label stored by the Pokémon TCG API. The score is an ordinal assigned to that label — Mega Hyper Rare and Hyper Rare 100, Special Illustration Rare 96, Rare Secret 92, down to Common 6. Unlisted labels score 18. The same label always shares a score. Ties break toward a plain collector number above the printed total, then a higher collector number. This is not a pull rate or a price.
