How to Judge a Card Pick

A reward-screen choice is stronger when the card's exact mechanics and the state of the current deck point in the same direction.

Context matters

Signals Behind a Pick

Skipping is a decision

A Reward Does Not Require a Pick

Adding a card changes every future draw. A card that looks individually strong can still make the deck worse when it does not solve a current problem or depends on support the deck does not have.

That is why SpireGenius separates the card database from the decision layer: exact game data is the starting point, not the final answer.

Card Pick FAQ

Should I take a card at every reward screen?
No. Adding a card has an opportunity cost because it changes what you draw later. A card should improve the deck you have or solve a problem the deck still has; skipping can be the stronger choice when it does neither.
Why can the same card be a good pick in one run and a skip in another?
Card value changes with character, current deck, relics, existing powers, energy, draw, and the problems your deck still needs to solve. SpireGenius treats the card as one part of that larger state rather than assigning every copy a universal answer.
Where should I go if I only want the exact game data?
Use the Cards database. Pick pages and decision tools are for the next question: what that data means for the choice you are making.
Why SpireGenius exists

Game data tells you what a card does. SpireGenius helps you decide what to do with it.

Use the database for exact values and relationships, then move into builds, synergies, and deck evaluation when the question becomes take, skip, or build around.
