Clash Royale Deck Analyzer & Builder

CR Deck Builders is a free Clash Royale deck builder and analyzer. Pick 8 of all 121 cards and it instantly checks your average elixir, offense–defense balance, win condition and weaknesses. Evolutions, Heroes and Champions are supported, and finished decks can be sent to the game in one tap.

The basics of building a strong deck

An easy-to-pilot deck balances a win condition that attacks towers, defense to absorb pushes, anti-air, and cheap cards to keep the hand cycling. Average elixir usually lands between 2.8 and 4.2 — lighter decks press with tempo, heavier ones hit harder per push. The analyzer puts your deck’s strengths and weaknesses into words from exactly this viewpoint.
