Free Run Tool

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.

Compare exact fields first. The stronger pick still depends on your deck, route, Energy, and next fight.

How to use the result

Facts first, run context second

1. Check timing

Can you afford the Energy or HP cost on the turn the option matters?

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.
