STS2 Shop Card Helper FAQ
Quick answers about how this shop evaluation tool works.
What does the STS2 Shop Card Helper do?
This tool evaluates every card in the Slay the Spire 2 shop against your current deck, relics, character, and act, and tells you whether each one is worth buying.
How is it different from the Reward Card Helper?
The Reward Card Helper picks one winner from a set of free options. The Shop Card Helper evaluates each card independently — every card gets a buy verdict so you can decide where to spend your gold.
Does it consider my deck size when rating shop cards?
Yes. Larger decks get stricter thresholds. A mediocre card that might be acceptable free gets a 'Pass' verdict in the shop because gold is limited.
Can I import my run data from GS Sync?
Yes. GS Sync automatically sends your current deck, relics, and shop cards to the helper. Connect GS Sync and visit the shop screen to trigger an instant import.
