## What is Card Hand Probability?

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.

Save decks for your next build
Save up to 3 named decks for free. Open, edit, duplicate and search by name. Your working draft is stored separately on your device so you can resume after an interruption, without using a saved deck slot.
Copy a text backup of your saved decks to keep in a note or file, and import a copied backup later.

9 interface languages
Japanese, English, Simplified Chinese, Traditional Chinese, Korean, Spanish, Brazilian Portuguese, French and German. Card and deck names stay as you entered them.

Optional paid features
Additional saved deck slots and ad removal are available through in-app purchases. Each slot purchase adds one slot.

This app calculates opening hands and a single redraw under the conditions you set. It does not predict play sequences or match win rates.
