This calculator allows Magic: The Gathering players to see the real-time average number of mana producing sources present. You should expect to see this in your hand, based on the number of cards drawn.

The math is simply based on the Hypergeometric Cumulative Probability rule that states P (X >= 1). This implies that probability is greater than or equal to 1.

This app will also help you calculate the number of lands for your MTG decks in sealed tournaments. Mana Calculator offers you with choosing different lands to your deck: white, red, blue, black, green and colourless.

An application is comparatively easy to use for beginners and advanced MTG players in sealed games (drafts, pre-releases, etc). All you need to do is to:

1. Set how many lands you would like to have in your deck/ library.

2. Accordingly count the number of mana symbolic cards in your deck and then move the spinner likewise.

3. Lastly, check how many cards of selected colours should be added to the deck.

In addition to this, you could also check which guild you are from. The Mana Calculator was written as a part of an extension of the MTG Tournament Calculator.
