Clash Royale Deck Checker
Load your decks
Your tag is under your name in game, on the main screen.
How does the deck checker work?
Paste a player tag or build a deck by hand and the checker scores it on what it can and cannot deal with: elixir cost, cycle speed, how it answers air, tanks and swarms, and how the eight cards work together. Every score comes from win rates measured across real battles, so it reflects what the deck does on ladder rather than how it looks on paper.
Load from a player tag
Enter any player tag and the checker pulls the decks that player has actually been using from their battle log, so you can check your own or take apart the deck that just beat you.
Fix it without leaving
Open the builder inside the checker and change the deck here: the four scores, the elixir and the cycle move with every swap, and sorting the card list by Suggested orders it by what actually wins next to the cards you are keeping.
Everyone who beat you, scored
Under your own decks sits every deck you ran into recently, each one scored the same way. Handy after a losing streak: it tells you whether that PEKKA bridge spam is actually a monster or whether you just kept giving it free elixir. Tap a name to open the profile behind it.
Questions people ask
Where do the deck checker scores come from?
From win rates measured across real ladder and tournament battles, not from a hand written rating per card. That is also why the scores move after a balance patch without anyone editing them.
Can I check another player's deck?
Yes. Enter their player tag and the checker reads the decks from their recent battles. You do not need to be that player and nothing is stored against their account.
My deck scores badly but I keep winning. Is the checker wrong?
Probably not, and neither are you. The scores describe the deck against the whole field, while your ladder run is a few dozen matches against whoever you met. A deck with one bad category wins comfortably until it runs into the matchup that exploits it.
Does the checker account for card levels?
The scores are about the deck, not the collection: they measure how the eight cards work together, which does not change with levels. Load your card levels in the deck builder if you want to see what is realistic to play right now.
