Booster Pack Guide

What Are Booster Packs?

Booster packs are the two items that always occupy the pack slots in the shop. Purchasing one opens it immediately: you are presented with several cards and must choose one or two to keep (or skip all of them if nothing is useful). Unlike buying a card directly from a card slot, packs offer a draft — more options visible at once means a higher chance of finding exactly what your build needs.

All 5 Pack Categories

1. Arcana Pack

• Contents: Tarot cards (22 Major Arcana)
• Purpose: Gain immediately usable Tarot cards
• Use cases: Deck sculpting via card destruction, rank conversion, and suit swapping; multiplier boosts from the Empress and The Fool

2. Buffoon Pack

• Contents: Joker cards
• Purpose: Add jokers directly to your run
• Use cases: The single most impactful pack type. Jokers are the primary engine of every build

3. Celestial Pack

• Contents: Planet cards (12 varieties)
• Purpose: Gain immediately usable Planet cards that level up a hand type
• Use cases: Stack levels on your primary hand type; pairs excellently with the Observatory voucher

4. Spectral Pack

• Contents: Spectral cards (18 varieties)
• Purpose: Apply powerful one-time effects immediately
• Use cases: Low drop rate but extremely high ceiling — a "Soul" card can hand you a Legendary joker

5. Standard Pack

• Contents: Standard playing cards (may include enhancements, seals, or editions)
• Purpose: Add cards to your deck
• Use cases: Low priority by default due to deck compression principles; useful when you specifically need cards of a certain rank or suit

The 3 Pack Sizes

Size	Cards Shown	Cards Chosen	Notes
Standard	3	1	Most common
Jumbo	5	1	Wider selection than Standard
Mega	5	2	Two picks — highest value, lowest drop rate

• Value order: Mega > Jumbo > Standard (drop rate is the inverse)
• Mega Buffoon is the most powerful pack in the game — two jokers from one purchase

Purchase Priority

Highest priority: Buffoon packs (especially Mega) Jokers are the foundation of your scoring engine. Every opportunity to add a joker is an opportunity you cannot afford to pass up casually. Even a mediocre joker often synergizes with what you already have.

Situational priority:

• Celestial packs: Buy when you are actively leveling a focused hand type
• Arcana packs: Buy when deck sculpting is needed (destroying dead cards, converting suits or ranks)
• Spectral packs: Buy when your jokers are already strong and you want to push them further

Lowest priority: Standard packs Adding cards to your deck dilutes consistency. The exception is when you need a specific suit or rank that your current deck lacks, or when you are hunting for an enhanced card or a Negative-edition joker.

The Special Value of Spectral Packs

Most Spectral cards offer powerful one-time effects, but the "Soul" card stands apart entirely:

• When "Soul" appears, it transforms one of your existing jokers into a Legendary Joker
• There are 5 Legendary Jokers: Caino, Triboulet, Yorick, Chicot, and Perkeo
• These are among the most powerful jokers in the entire game, each with effects that compound dramatically over the course of a run

Even without the Soul card, Spectral packs contain effects that cannot be obtained elsewhere — making them worth buying once your joker lineup is established and you are looking for ways to amplify it.

Decision Flow for Each Shop Visit

Use this mental checklist when evaluating packs in the shop:

1. Is there a Buffoon pack? If yes and a joker slot is open — buy it first
2. Are joker slots full? If yes, skip Buffoon and Spectral packs until a slot opens
3. Do you have a fixed primary hand? If yes, check whether a matching Celestial pack is available
4. Is your deck bloated with dead cards? If yes, prioritize an Arcana pack for sculpting
5. Are your jokers already strong? If yes, a Spectral pack becomes a high-value option for amplification
6. Only Standard packs remain? Buy only if you specifically need a card of a certain rank or suit
