Arena Tracker was built specifically for Arena players and offers many helpful features:
Hero win rates by class when picking a hero, using global HSReplay stats and your personal stats.
Card scores during drafts from Firestone, HSReplay, and HearthArena.
Deck score, which is the average of your card scores.
Deck Weight, a measure of how heavy your deck is.
Synergy within your deck.
Mechanics summary: shows the number of AOE, taunts, healing, draws, pings, removal, hard removal, and reach in your deck.
Drop counts: how many 2‑drops, 3‑drops, and 4‑drops your deck contains.
Arena Tracker uses the HearthArena tier list, HSReplay win rates and Firestone win rates during drafts. You can choose your preferred source in Config Tab -> Draft section.
When you enter the arena, your arena deck loads automatically in the Player Deck window. If you exit the arena, the deck you were using before will be loaded, provided it’s saved in your Arena Tracker collection.
When you reach the hero selection screen, AT shows class win rates from HSReplay and (Patreon only) your personal win rates per hero.
If you forgot to open AT while on the pick your hero screen, just go back to the main menu in Hearthstone and enter arena again; this will trigger AT to recognize the heroes.
Note: Don’t use Force Draft here—it’s meant for card drafting.
Once you pick a hero or resume a draft, a new Drafting Tab appears automatically.
Note: If card positions were misdetected or if you've manually readjusted your deck and want synergies to be recalculated, use Force Draft to restart drafting.
Arena Tracker downloads the class card images (if needed), showing progress via a loading bar. These images save to USER/Arena Tracker/Hearthstone Cards.
AT goes through two phases to detect the cards on screen:
First, it tries to locate the cards by comparing your screen with a predefined template. During this phase, the card selectors are disabled, because AT isn’t reading the cards yet — it’s only trying to detect their position.
Once the location is detected, AT will use it for the rest of the draft. From this point on, it starts reading the cards, and after a few seconds, the best candidates will appear in the selectors.
On the first pick, AT shows the scores of all components in every legendary bundle. Keep in mind that the scores displayed below the cards, in this case, represent the average of all cards in the bundle, including the main legendary one.
When opening a bundle, the scores will be hidden so you can easily pick the bundle in HS. If you want to show them again, click the refresh button in the AT Draft tab.
Once picked, AT will show you the following message:
If you skip this step, the bundle’s cards won’t count toward synergy analysis and they won't appear in your deck list.
The tab presents your current pick and a summary of deck mechanics.
At the top:
Rescan button – re-scans the screen (useful if something obscured cards).
Deck score average – displayed with Firestone, HSReplay, and HearthArena ratings.
Below every card you can see its score given by Firestone, HSReplay and Heartharena.
Below each card:
Scores from Firestone, HSReplay, and HearthArena.
HSReplay win rates are shown as:
Included Winrate: It's the winrate of the card considering all the matches in which that card is part of the deck.
Played winrate: It's the winrate of the card considering only the matches in which that card is played.
Display format: (Included% – Played%). The overlay shows Included rates.
Firestone scores are shown as included winrate only.
At the bottom you can see a summary of the mechanics included in your deck.
Each drafted card appears in a combobox, allowing manual correction if misidentified.Typing a Card
If the card you are looking for is not present in any of the options, you can manually enter its name in the input field that appears at the top after you interacted with a combobox.
You don't need to type the exact name, just part of it separated by spaces. To find "Mistress of Mixtures", we can type "mix" or "mix mis" or "tress ixtur".
The card, greyed out, will be changed in the last combobox you interacted with as you type.
Keep typing until you see the one you want. Then press enter and the winrates and synergies will be loaded.
After reading the card image, AT will locate and read the mana cost and rarity of the card; if they are different, AT will select the best card image that meets the criteria (mana and rarity) and will warn you.
To verify that the card is correct and show its scores you can:
Click the card with the tag (Is this your card?).
Click the arrow button below.
Just move the mouse over the (Is this your card?) card and leave. This way you avoid clicking near the real hearthstone cards, which is dangerous
To select a different card you can look in the combobox or manually type the correct card in AT main window like explained in the sections above.
The goal of all this, is to be certain as users that if AT show the scores of a card, it's 99.9% the correct card.
With the overlay enabled in Config -> Draft:
The Highest score will be surrounded with spikes.
You’ll see Firestone, HSReplay, and HearthArena scores beneath each card.
If Hide Scores is enabled, scores are replaced with a “?” and revealed on hover—for drafting practice.
Card synergies appear below cards (Patreon only).
Each card’s mechanics contribution is also shown (Patreon only).
If HSReplay or Firestone has low data for a card (< 2,000 plays), AT indicates this:
Score background fill shows data volume.
A notice appears in the draft tab label.
Below the winrates scores if you are hovering your mouse over any of the scores.
Clicking an HSReplay score opens the Arena section on HSReplay.net with your class and chosen picks preloaded for deeper stats.
Enabled via Config -> Draft overlay:
Displays icons above cards illustrating various mechanics.
Hover over the green question mark to see this legend at any time.
Minions: Number of minions in your deck.
Spells: Number of spells in your deck.
Weapons: Number of weapons in your deck.
Mana average: Average of the mana cost of all your deck. Any card which mana cost exceed 10 will be counted as a 10 mana cost card (like giants). Some cards mana cost might be adapted to a more logical value (Nerubian Prophet is considered a 3 mana cost card).
Deck Weight: It shows how heavy your deck is by combining deck mana average and cards that generate/draw other cards in a number that should represent your modified mana average.
Deck Score average: Average score of your deck acording to Firestone, HSReplay or HearthArena winrates/tier list. The assistant that will be used for the average deck score during a draft will be the one selected in the AVG combobox in config tab.
Reach: Number of cards that can deal 2 or more damage directly to the enemy hero. Stealth minions are considered reach, along with charge minions and direct damage effects.
Taunt: Number of taunts or taunt generators in your deck.
Survival: Number of cards that heal your hero.
Draw: Number of cards that allow you to draw more cards, discover cards or generate cards that go to your hand.
Ping: Number of cards that can deal 1 damage. Ping cards need to be proactive. Cards that deal random pings are also considered pings unless they do it through deathrattle (deathrattle is not proactive, doesn't have effect the turn you play it). Same proactive rule is applied to removals and hard removals.
Removal: Number of cards that can deal 2 or more damage to an enemy minion.
Hard removal: Number of cards that can destroy an enemy minion. Cards that deal a huge ammount of damage are also considered hard removal, like meteor or pyroblast.
AOE: Number of AOEs in your deck. For a card to be considered AOE needs to deal damage to at least 3 enemies. Arcane missiles is considered AOE but it's in the limit. Dearthrattle minions with AOE are considered AOE only if deal more than 1 damage AOE.

Deck Weight will show how heavy your deck is by combining your deck mana average and cards that generate/draw other cards present in your deck.
Imagine we have a deck with no cards than draw/generate cards. In this case setting how heavy the deck is would be easy, just calculate the mana average of all your 30 cards and that number would represent your deck weight.
In the case of cards that draw/generate cards, their mana has to be corrected to include the mana of the extra cards, let's see some examples:
Hallucination is a 1 cost card that discover a card. Generated cards are considered as 4 cost cards. This means the mana cost of Hallucination for deck weight calculation is 1 + 4 = 5
Arcane Intellect is a 3 cost card that draw 2 cards. We need to calculate the average mana cost of a card in your deck, and that will be the cost of the 2 drawn cards, lets say is 4.5 for this example. This means the mana cost of Arcane Intellect for deck weight calculation is 3 + 4.5 + 4.5 = 12
Once you get the corrected mana cost of every card in your deck you can calculate their average. This number is the one you will see inside the deck weight element.
The bounds of deck weight are 3 and 5.5:
If deck weight is less or equal than 3 the element will be shown as empty, indicating your deck is way too light.
If deck weight is more or equal than 5.5 the element will be shown as full of lava indicating your deck is way too heavy.
Also, some cards might have a different cost that the written on the card, this is because in a real game, those would be played by less mana. For instance, sea giant is considered a 6-mana card for deck weight calculations.
Instead of showing the data from the 8 mechanics you might prefer to track the ammount of 2-drops, 3-drops and-4 drops you have in your deck during the draft. To do so check the option Show Drops in the Draft section of the config tab. Either way all of them will always be shown at the bottom of the draft tab.
What is a 2-drop? A 2-drop is a card that you play on your turn 2 and give you enough tempo to fight for the board, not every 2-mana card is a 2-drop.
Turn 2, 3 and 4 are very important turns in arena and when drafting a deck you need to make sure you have enough 2-drops, 3-drops and 4-drops to not fall behind.
An average arena deck should have the following ammount of drops:
2-drops: 5-6
3-drops: 4-5
4-drops: 3-4
With this overlay active you will be able to see as part of the mechanics overlay (above the cards) and in the drafting tab the ammount of drops your deck has. Its border will indicate:
Red border: Your deck doesn't have enough drops, for the ammount of cards you have already drafted.
Green border: The number of drops is ok for now.
When you get offered 3 new cards, as part of the mechanics shown below the score you will check if that card is a drop. Its border will indicate:
Red border: You have more than enough drops for a 30 cards deck so try to pick as few of this drops as you can for the rest of the draft. Consider not picking this card.
No border: The number of drops in your deck is ok for now, you can pick more if this card it's worth it but there's no hurry for now.
Green border: Your deck doesn't have enough drops, for the ammount of cards you have already drafted. Consider picking this card.
To make space to show the drops mechanics in the mechanics overlay I've hidden Reach, Taunt and Survival as they aren't as important as the other 5 (Ping, Removal, Hard removal, AOE and Draw).
