Pick Card Rewards That Help Your Next Fight

Before taking a Slay the Spire 2 card reward, open your deck and name something the next card should help you do. You might need damage sooner, more reliable defense or a way to use the cards already in your hand. Start with the deck you have.

Find the problem behind the last fight

Think about the turns that cost you health. Did you lack useful cards, draw them too late, or spend Energy in the wrong order? Low HP alone does not prove that you need another Block card. A fight that lasted too long may instead call for damage. Use the turn planning guide to separate a missing tool from a sequencing mistake.

Look at your relics as well as your cards. Then compare the rewards with the next encounters on your route. You can decline a card reward with Skip, so you do not have to choose something merely because it is offered. Untapped.gg’s starter guidance

Ask what the card does when drawn

Picture the new card beside cards you already play often. Can you afford a useful sequence, or would it compete for all your Energy? A strong effect can still be awkward when the rest of the hand needs the same resource. Read additional costs and conditions before choosing it.

Immediate damage helps you act without setup. Scaling improves your output over time, but setting it up can cost early momentum. Ask whether the next fights give that effect time to help. Adding a card can also delay drawing existing cards; extra draw and other effects change that tradeoff. Baalorlord’s deckbuilding concepts

Take a card when you can explain its useful job. If it needs several missing pieces before doing anything helpful, consider passing. A promising interaction with cards or relics already owned is a stronger reason than hoping the rest of a combo arrives later.

Compare taking, skipping and upgrading

Skipping leaves the current deck intact. It is worth considering when the offered cards duplicate jobs you already handle or make common hands harder to play. It does not mean that the smallest deck wins: a larger deck can carry answers your smaller deck lacks.

Smith at a Rest Site upgrades a card you already own. Inspect the upgraded text and ask how often that improvement will matter. Compare it with Rest using your remaining HP and upcoming encounters. The displayed options can change with other effects. Community wiki: Rest Sites

Use map routes and Rest Sites to work out which opportunities are actually reachable. A future upgrade is a possibility to plan around, not a reason to accept a card your deck cannot use yet.

Remove a card for a specific reason

At the Merchant, compare removal with the other purchases. Removal normally works once per shop, and later shop removals cost more. Read the price shown. Before removing a basic attack or defensive card, check that the deck still has enough of that job. Community wiki: The Merchant

Eternal cards cannot be permanently removed or transformed. This is a deck restriction, separate from Retain and Exhaust during combat. Read the keyword before planning a removal. Community wiki: keywords
