The best Hearthstone Deck Tracker overlay settings keep confirmed card information easy to scan while leaving the game board clear. Start with the exact deck you queued as your active deck, show your remaining cards and deck count, keep the opponent’s revealed cards visible, and hide probability or match-stat panels until you need them. Here, card counting means keeping track of cards you have seen or can infer from a known deck list. A tracker does not reveal an unrevealed card in your opponent’s hand.
This guide covers Hearthstone Deck Tracker (HDT) on desktop. Other trackers may use different controls. The layout labels and appearance can also change between HDT releases, so treat the settings below as a practical starting point rather than fixed screen coordinates.
| Overlay item | Starting setting | Use it for |
|---|---|---|
| Your deck list | Set the exact list as Active; show remaining cards and deck count | Checking what you can still draw |
| Your hand and deck counts | On | Tracking available cards and draws remaining |
| Opponent played cards | On | Reviewing confirmed reveals and key effects |
| Opponent hand and deck counts | On if useful; treat counts as context | Estimating how much information is unknown |
| Card probabilities | Off initially | Optional estimates, not confirmed hand contents |
| Win-rate and other match panels | Off during play unless you actively use them | Reducing distraction |
| Position and scale | Keep panels at the sides and outside the board | Making the overlay readable without covering choices |
If HDT shows only cards already played and not the cards left in your deck, check the deck state first. HDT distinguishes between a deck that is selected for viewing and one that is active for the current game. The official FAQ explains that the active deck is the list used for a match; selecting a deck can simply open it for inspection. Open your deck list, find the version you actually queued, and use its Active or Use control. Make sure it includes any last-minute card changes.
An active deck is the foundation for useful remaining-card tracking. If the list is wrong, every “still in deck” count can be wrong even when the overlay is updating correctly. The FAQ also notes that an Active deck is needed for the remaining-card display. See the official HDT FAQ for the current troubleshooting notes and deck-state explanation.
For your side of the match, prioritize the cards still in your deck, the number of cards left, and your hand count. Those details help answer practical questions: Is a specific answer still available to draw? Have both copies of a card already appeared? How many draws remain before fatigue becomes relevant? You do not need every match statistic on screen to answer those questions.
For the opponent, the most reliable overlay information is a card that has been visibly played or otherwise revealed, plus the opponent’s hand and deck counts when HDT tracks them. Keep the played-card history prominent if you are counting removal, board clears, or threats. A count tells you how many cards the opponent holds; it does not identify them. The HDT project documentation describes tracking cards remaining in your deck, drawn cards, opponent plays, hand and deck counts, and probabilities.
HDT’s overlay guide documents that overlay elements can be repositioned and that displayed deck-list items can be enabled or disabled separately. Use those controls to keep only the information that affects a decision. Exact labels can differ by release.
Probability panels are optional estimates. They may look precise, but they are not a readout of a hidden hand. The HDT FAQ describes its opponent-card probability calculation in terms of the number of cards left in the opponent’s deck and the number already in hand. That estimate is only as useful as the information the tracker has about the opponent’s list and the events it has recorded.
Randomly generated cards, Discover choices, cards shuffled into a deck, copied cards, deck-changing effects, or a missed tracking event can make a simple count incomplete. For a clean setup, keep confirmed plays visible and leave probability widgets hidden. If you later turn them on, read them as “possible under these assumptions,” never as confirmation that a specific card is in hand.
Unlock the overlay when you need to adjust it, then move your deck panel toward your side of the screen and the opponent panel toward the opposite side. Leave the center of the board open. Your hand, hero powers, card-choice screens, secrets, and turn timer should remain unobstructed. HDT’s published overlay instructions describe moving the overlay and changing which deck-list items appear.
There is no best universal scale percentage. Resolution, display scaling, monitor size, and viewing distance all affect readability. Make small changes: shrink panels until they stop competing with the board, then enlarge only the text or card list you cannot read comfortably. If a panel becomes too long, hide lower-priority rows instead of covering game actions. Keep the layout in the same place between matches so you can glance at a count without searching the screen.
Also avoid stacking multiple trackers or companion overlays over the same corner. If the overlay slips behind Hearthstone or disappears, use the troubleshooting steps in the HDT FAQ; the cause may be visibility or game-detection behavior rather than a card-counting setting.
In a practice or casual game, check three things: the active list is the one you brought; cards you draw or play move to the appropriate state; and cards the opponent visibly plays appear in the history. Confirm that the panels stay out of the way when a card-choice or other full-screen decision appears. Do not trust a stale overlay as current information.
If card history stops updating, restart Hearthstone and HDT, then check that the tracker is pointed at the correct Hearthstone installation and that game logs are being detected. The HDT FAQ has more detailed steps for card-detection problems, including checking the game path and log files. Once tracking resumes, verify the count against what you can see in the match before acting on it.
A deck tracker can organize information available from the game and supported logs. It cannot reliably name an unrevealed opposing card simply because that card would make sense strategically. Generated, shuffled, copied, returned, or otherwise transformed cards can also complicate a simple remaining-card list. Treat the game’s visible information as authoritative when effects change a deck.
For organized play, check the event’s rules before using any tracker. Blizzard’s current published Hearthstone Tournament Player Handbook, Section 5.10, allows deck-tracking software in covered online tournaments only under stated conditions, including event permission and limiting the tracker to information observable from the unaugmented game interface. The Blizzard End User License Agreement also restricts unauthorized software that collects or mines platform information. Tournament policies can vary, so ask the organizer if a feature is unclear.
A good Hearthstone Deck Tracker overlay makes confirmed cards quick to count, keeps the board readable, and leaves uncertainty visible. Use an accurate Active deck, keep the revealed-card history in view, and add estimates only when they help you make a decision.
