MTG Deck Mana Curve & Probability Calculator

How to calculate mana curve?

The Average Mana Value (MV) is a key metric that determines the speed and consistency of your Magic: The Gathering deck. It measures the mean casting cost of all non-land cards to help you optimize your resource management.

The standard formula is: Avg MV = Total MV / Total Spells

Using the MTG calculator: an example

Imagine a standard 60-card deck that utilizes 24 lands and 36 spells (including creatures, sorceries, and artifacts).

Step-by-step calculation:

1. Calculate the sum of the Mana Values for all 36 spells in the deck.
2. Divide that total sum by 36 (the number of spells) to find your average.

Optimizing land ratios based on this result ensures you have enough mana to play your cards on curve while minimizing the risk of mana flood or screw.

Frequently Asked Questions

What is a good average mana value?
For most competitive decks, an average mana value between 1.8 and 3.5 is ideal. Aggro decks prefer the lower end, while midrange and control decks often trend higher.

How many lands should I run?
A base of 24 lands is standard for 60-card decks. You should scale this up for high-cost control decks or down for low-curve aggressive strategies.

What is the hypergeometric distribution?
It is a mathematical formula used to calculate the probability of drawing specific cards from a deck without replacement. It is the primary tool for determining mana base consistency.
