Calculate the percentage that a card combination will occur in the first cards dealt off the top of the deck.
To calculate the chance of drawing your combination, you need to describe your deck and your combination.
There is one row for each type of card. In the first column, you can enter the name of the card. In the second column, enter the number of cards you have in your deck. In the third column, enter the number of cards you want in your hand for your combination.
For example, if you are calculating the likelihood of a channel/red X spell combination, you need your one channel (1:1), one of your eight red X spells (8:1), one mountain (12:1), two forests (12:2), and none of your other cards (27:0).
Make sure the entire deck is described. The sum of the deck column should be the size of your deck. You must draw at least as many cards as are in your combination, but not more than are in your deck.
