MTG Probability

MTG Probability is a simple yet powerful probability calculator for serious Magic: The Gathering and other card game players. See the screenshots for what's possible.

FEATURES AND USAGE

You specify four to eight numbers.
- Total number of cards in your library
- Total number of cards you draw from your library
- Number of specific card A in your library
- Number of specific card A you need to draw
And optionally,
- Number of specific card B in your library
- Number of specific card B you need to draw
- Number of specific card C in your library
- Number of specific card C you need to draw

And MTG Probability immediately shows the probability of drawing needed (or more) numbers of cards A, B and C. You can change those numbers by tapping the -/+ buttons and see how the probability changes accordingly. You’ll find this more convenient than reading tables of numbers.

WHY PROBABILITY IS IMPORTANT

Probability by itself does not directly answer any questions in deck building or game playing. That requires a comprehensive judgement. Rather, knowing the exact probabilities for various situations makes your intuition more accurate and makes you able to make better comprehensive decisions.
