Frequently Asked Questions

Where does the win rate data come from?

All battle data comes from the official Supercell API — real Ranked and Trophy Road battles played in the game.

Every hour we process a fresh batch of those battles to:

• find the decks players are winning with
• count wins and losses for every card and deck

Which battles are included in the stats?

We only count Ranked and Trophy Road (ladder) battles. Challenges, 2v2, Party Mode, and other event modes are not included.

The win rate you see is both modes combined. We do not split Ranked and Trophy Road into separate numbers.

What do "win rate" and "battles" mean?

Win rate is the percentage of battles won out of all battles played. For example, 53% means the deck won 53 of every 100 battles.

Battles is the total number of battles played with that card or deck in the time period you selected.

We only count the result, not the crown score — a 3–0 and a 1–0 both count as one win.

What do the 24h, 7d, and 30d buttons do?

They set the time window for the battle stats on the page: win rate, battles, usage rate, rank, and the per-arena breakdown on a deck page. 24h is the last 24 hours, 7d the last 7 days, and 30d the last 30 days.

Your choice is remembered as you browse. We default to 30d because it gives the largest, most stable sample.

The trend charts always show the last 30 days, no matter which button is selected.

How recent is the data behind the stats?

We only use battles inside the window you pick. Older battles drop out automatically, so the numbers follow the current meta instead of stacking up forever.

How often are the stats updated?

We pull fresh data from the API and recalculate every deck and card once an hour.

A full refresh takes about 10 minutes. Each page shows an "Updated … ago" label, and a few numbers may shift slightly while an update is running.

What do "usage rate" and "rank" mean on a card?

On a card page you will see two extra numbers besides win rate and battles:

• Usage rate — the share of player decks that included this card in the selected period.
• Rank — the card's place by win rate among others of the same type: base cards vs base cards, evolutions vs evolutions, heroes vs heroes. Cards with too few battles are left out.

Is a card's win rate the same as a deck's win rate?

No — they measure different things:

• A deck's win rate covers battles played with that 8-card combo. On the main deck page this includes every evolution and hero version of those cards.
• A card's win rate covers every battle that card appeared in, no matter the other seven cards around it.

So a strong card can still show a modest win rate if it is often used in weaker decks, and a high card win rate does not mean that card won those battles by itself.

Why do evolutions and heroes have their own stats?

Evolved cards and hero cards play very differently from the base versions, so we track each one as its own entry, with its own win rate and rank.

That is why the same card can appear more than once — a base card, its evolution, and its hero each have their own page and numbers.

What is a deck variant?

A variant is the same eight cards with a different evolution or hero combination.

Variants live on the Variants tab of the main deck page. They do not appear in the main Best Decks list, unless you filter by that exact evolution or hero.

The main deck's win rate covers the whole 8-card combo. A variant's win rate covers only that specific combination.

What is the deck analysis score?

The overall score out of 10 on a deck page rates the deck's Attack, Defense, Synergy, and Versatility based on how its eight cards work together.

It is a structural rating of the card composition. It is not based on battle data, so it does not change when you switch the 24h / 7d / 30d period.

How do decks get onto DeckMelon?

Decks come from popular Ranked and Trophy Road play. A deck is added only after it has enough battles for stable stats.

Once a deck reaches 50 battles in the last 30 days, it gets the Current Meta tag so you can spot what people are playing right now.

Can I submit my own deck?

No. DeckMelon is not a deck-upload site. We only add decks that already show up in popular Ranked and Trophy Road play, once they have enough battles.

If you spotted a bug or have a suggestion, use the Contact page.

How do I copy a deck into Clash Royale?

Open a deck and tap Copy Deck. That uses the official Clash Royale link and fills the deck in the game. The game needs to be installed — on a phone it usually opens straight away; on a computer you need the Clash Royale client.

For a 2v2 pair there are two copy buttons, one for each player.

What do Trending and Latest mean?

Trending sorts by how many times each deck was viewed over the last 30 days, not by win rate. A popular deck can sit above a higher win-rate deck that fewer people opened.

Latest shows the newest decks added to DeckMelon.

How do arena filters work?

The arena filter on Best Decks shows decks you can play at that arena, based on when the cards unlock. It is not a "best win rate at this arena" ranking.

To see how a deck actually performed at each arena, open the deck and use the By Arena breakdown in its battle stats. Those numbers come from the same Ranked and Trophy Road battles.
