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

2. Name the job
Decide whether you need damage, Block, scaling, draw, or consistency.
3. Check the route
Value the next elite, boss, shop, and campfire instead of an abstract tier.
