All-Out Attack · Slay the Spire: Cost and base card values

Using this reference

Before adding All-Out Attack 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.

One useful comparison

For Base resource cost, All-Out Attack is listed at 1, compared with 2 for A Thousand Cuts: a difference of 1. This compares that field in the recorded variants only. Read the other fields before deciding whether the trade-off matters to your use.
