Card System

The core of Monster Mashup is its unique, procedurally generated card system. Every card you pull is different, with stats that define its performance in production and battles.

Rarity Tiers

There are 5 rarity tiers, each with distinct stat potential and drop rates:

Rarity	Base Min	Base Max	Color
Common	5	30	Gray
Uncommon	15	50	Green
Rare	30	70	Blue
Epic	45	85	Purple
Legendary	60	100	Gold

Overlapping Ranges

Monster Mashup uses an overlapping stat system. This means a "God Roll" Common card can actually beat a poorly rolled Uncommon card! This makes every single pack opening exciting.

Monster Attributes

Monster attributes are the primary factor in determining a card's Production Rate and Battle Performance.

Attribute	Icon	Description
Cuteness	🥰	Pure adorable energy. Beats Silliness in battle.
Scariness	😨	Spooky and intimidating. Beats Cuteness in battle.
Silliness	🤪	Pure chaotic fun. Beats Scariness in battle.

Specialization Bonus

Each monster has a Specialization (one of the three attributes above). The card's highest-rolled attribute determines its primary class, granting a 1.2x multiplier to that stat during battles of the matching challenge type.

Formula:Specialized Stat = Base Roll + (Base Roll * 0.2)

This ensures that cards are always strongest in their intended attribute, giving them a clear role in your team.

Production & Economy

Cards generate daily gold production for your account. Production is calculated using multiple factors:

Base Production Rate

A card's base production is calculated based on its Rarity and the Sum of its Attributes.

• Common: 10-20 coins/day
• Uncommon: 25-50 coins/day
• Rare: 60-120 coins/day
• Epic: 150-300 coins/day
• Legendary: 500-1000+ coins/day

Star Rating Multiplier

• Star rating (1-5 stars) multiplies production:
  • 5 stars: ×1.3 (+30%)
  • 4 stars: ×1.15 (+15%)
  • 3 stars: ×1.05 (+5%)
  • 2 stars & 1 star: ×1.0 (no bonus)

Variant Production Modifiers

Percentage Bonuses:

• Golden 💰 variants: +100% production multiplier (doubles production rate)

Flat Gold Bonuses: All special variants provide a flat daily gold bonus separate from the percentage-based production:

• This bonus scales with card rarity (Common: ×1, Legendary: ×12)
• See Special Variants for the complete bonus table

**Example:**
- Legendary Golden card with base production of 10 gold/day and 5 stars:
  - Base: 10
  - With 5 stars: 10 × 1.3 = 13
  - With Golden variant: 13 × 2.0 = 26
  - Plus flat Golden Legendary bonus: +720
  - **Total: 746 gold/day!**

::: tip Variant Cards Are Always Valuable
Because of the flat gold bonus system, even low-production common cards with rare variants (like Glitch or Void) become highly valuable for your daily income!
