Blasphemy · Slay the Spire: Cost and base card values

Using this reference

Before adding Blasphemy to a deck, read its cost alongside its type, target and recorded mechanics. A cheap card is not automatically efficient if it needs another card to do useful work. Likewise, a more expensive card may fill a role that your current list lacks.

Compare cards within the same ruleset and character or class restrictions. If an upgraded form is listed, compare that form separately rather than mixing its values with the base card. These fields help you inspect a choice; they do not simulate draw order, a full turn or an opponent’s response.

Before you choose

For Blasphemy, start with these recorded details: Base resource cost: 1, Card type: Skill, and Rarity: Rare. Check them together rather than treating any one as a complete description. If your game shows different values, compare the selected variant and source version before relying on this record.
