Spectral Cards are rare and powerful consumables that offer unique, often game-changing, effects. They can appear in special Spectral Booster Packs or through certain Jokers. Their effects can range from adding powerful card enhancements (like Steel or Stone cards) to completely overhauling your hand or deck. Due to their rarity and potency, use them wisely. Some Spectral cards have drawbacks, so always read their descriptions carefully before using them.

Examples of Spectral Card effects:
- Ectoplasm: Add a random 'Spectral' card to your hand.
- Plasma: Make a random card 'Steel'.
- Void: Remove all cards of a specific rank from your deck.
- Soul: Make a random card 'Stone'.
- Poltergeist: Duplicate a random Joker.
