Deck-u-lator calculates the percentage that a card combination will occur in the first cards dealt off the top of the deck.

Using Deck-u-lator for mana calculations

SuperDad's Probability Calculator is a Java calculator that calculates probabilities of getting enough mana. SuperDad calculates drawing with replacement instead of the multivariate hypergeometric distribution without replacement. It takes as input:
  • deck size
  • mana in deck
  • cards to be drawn
  • mana wanted
This can be done using Deck-u-lator with only two types of cards: mana and other

Example 1

if you want to know how what the probability of playing lands in each of your first 4 turns (you don't go first, 4+7=11 cards drawn), in a deck of 60 cards where 20 are land. Try it! If you want better than about a 50/50 chance of playing lands on each of your first 4 turns (to get that Juggernaut out), you need to add more land, elves, dark rituals, or something similar.

Example 2

You have 4 I-win-you-lose-super cards in your deck. What is the probability that you'll draw one of your super cards in the first 5 turns? (5+7=12 cards drawn. As before, other player draws first so you get to draw on turn 1, 60 card deck). Try it! You can improve your odds by adding impulse, intuition, or something similar.

Example 3

You are playing a 60-card white and red deck with 13 plains and 9 mountains. Your deck is loaded with WW creatures. What is the probability that you will be able to bring out one of these creatures on the second turn? Not good enough for a fast deck, you'd better put in more plains!! With Deck-u-lator we can also factor in the probability of drawing a WW creature to go with those 2 plains by adding a third card type.
