Compare Slay the Spire 2 cards and relics
Put two entries next to each other before a reward or shop decision. Check exact cost, class, rarity, text, upgrade, pool, and price without switching between tabs.
Quick rule: compare the job each option solves in your current run. A lower-cost card that fixes the next fight can be better than a rarer payoff with no support.

How to use the result
Facts first, run context second

Value the next elite, boss, shop, and campfire instead of an abstract tier.
