Mana Card Cost Calculator Custom Cards

This mana card cost calculator helps you determine the appropriate mana cost for custom Magic: The Gathering cards. By analyzing the card's power, toughness, abilities, and rarity, you can create balanced custom cards that fit within the game's economy.

How to Use This Calculator

To calculate the mana cost for your custom card:

Enter the card's base power and toughness values
Select the card's rarity (Common, Uncommon, Rare, Mythic)
Choose any special abilities the card has
Click "Calculate" to get the recommended mana cost

The calculator uses a weighted formula that considers the card's stats, abilities, and rarity to determine an appropriate mana cost. You can then adjust the result based on your playtesting and balancing needs.

Formula Explained

The mana cost calculation uses the following formula:

Mana Cost Formula

Mana Cost = (Power + Toughness) × Rarity Multiplier + Ability Points

Where:

Power = Card's attack value
Toughness = Card's defense value
Rarity Multiplier = 1.0 (Common), 1.2 (Uncommon), 1.5 (Rare), 2.0 (Mythic)
Ability Points = Sum of points for each special ability

This formula provides a starting point for mana cost determination. You may need to adjust the result based on your specific game balance needs and playtesting results.

Worked Examples

Example 1: Basic Creature

A common creature with 2/2 stats and no abilities would have:

Mana Cost = (2 + 2) × 1.0 + 0 = 4

Recommended mana cost: {2}

Example 2: Rare Creature with Abilities

A rare creature with 3/4 stats and two abilities (each worth 1 point) would have:

Mana Cost = (3 + 4) × 1.5 + 2 = 12 + 2 = 14

Recommended mana cost: {4}{4}{4}

Note

These examples show the base calculation. You may need to adjust the mana cost based on your specific game balance and playtesting results.
