Card Hand Probability vs Kakuritsu Kun

Check your chances of drawing key cards and make informed choices about card counts. Set the deck size, opening hand and success conditions to compare the consistency of your opening hands. Three steps: rules, cards, conditions • Set your deck size and opening hand size. • Choose no mulligan, one redraw after returning the whole hand, or one redraw excluding the whole hand. A redraw happens only when the hand fails your success conditions. • Enter names and counts for the cards you want to analyze. The remaining cards are grouped as Other cards. • Combine OR choices such as A or B with AND requirements such as A and B. Each AND row needs a separate physical card. If you add multiple success patterns, meeting any one counts as success. Read the probabilities clearly See the chance of meeting any condition, the chance of meeting none, and each condition's probability, displayed to three decimal places. With a mulligan, see the initial-hand probability and the gain from redrawing. Conditions can overlap, so their probabilities cannot be added together. Compare a one-card change Keep the deck size and rules fixed while adding or removing one copy. Choose which other card count changes in its place, then compare the before and after probabilities and the difference in percentage points. Apply the changed counts to your inputs.
