Opening hand probabilitiesThese are the probabilities of having at least one copy of a certain card in your hand on the early turns when you are mulliganning aggressively for the card. Note that number of copies does not have to be 1 or 2; for example you can use 5 if you have 5 one-mana drops and would like to see your chances of having at least one on turn 1.

Probabilities of drawing into a card This is a simple calculator to find the probability of having seen a card at a certain point in the game. It can be useful for figuring out problems related to mana-curve; for example how likely you are to have one of your 4 six-drops in your hand having seen 15 cards. Note that this calculation cannot be done based on the turn number because different decks will see a different number of cards based on mulligans and card draw.

Probabilities of having combosThese are probabilities for how likely you are to have combos in your hand at certain points in the game. Only 2 card combos are included since 3 card+ combos in Hearthstone are unrealistic and have negligible probabilities.
