Dreamcards Resource Preview Guide — Check Effects Before Playing
A direct, source-checked answer for using Dreamcards Resource Preview without inventing resource values, card combinations, or a full-release tier list.

Use Dreamcards Resource Preview before playing a card: the developer says it shows the effect on each game resource in advance, and it changes if your selected character changes what the card gains or spends. That turns a vague card description into a checkable decision; it does not make an old deck list valid for every build.
A repeatable preview check
- Select the card you are considering, then read the current Resource Preview before confirming the action.
- Note the selected character. The published update says character selection can modify gained or spent resources, so compare the preview again if you change character.
- Look for the active-character indicator. The developer describes a particle signal that communicates when an effect is active and whether the selected card will activate that character.
- If the character has a limited-use ability, read its counter before spending the card. A counter is evidence of remaining uses; it is not a promise that a different character follows the same rule.
- After the action resolves, compare the visible result with the preview and record the build if they differ. Keep the exact card, selected character, night or phase, and error text before calling it a bug.
What this prevents
Resource Preview is especially useful when a card may look affordable but a selected character changes the gain or cost. It also makes it easier to separate a deliberate modifier from a stale screenshot or a real mismatch. The official patch does not publish a complete resource formula, a card-by-card table, or the best time to use each effect, so this guide does not invent any of those values.
Dreamcards’ official pages describe action and buy phases, a day-and-night deckbuilding structure, and a seven-night run objective. Use the Dreamcards guide for that loop, then use preview to make one verified decision at a time.

Quick answers
How do I see a card’s resource effect in Dreamcards?
The official February Demo update says Resource Preview shows how a card affects each game resource before the card is used. Select the card and read the current preview rather than relying on an old screenshot.
Why did the Dreamcards preview change after I selected a character?
The developer says the preview updates whenever a selected character changes the amount of resources gained or spent. A changed preview can therefore be an intended modifier, not necessarily a bug.
How can I tell whether a character effect is active or limited?
The same update says active characters use a particle indicator, and limited-use abilities display a counter for the number of uses. Check both before spending the card that triggers the effect.
