Decks for Arena 15 — Miner's Mine (5,000–5,500 trophies) are sourced from two datasets: curated guides selected for deck consistency, card synergy, and proven ladder performance in this trophy range, and a snapshot of the highest win-rate configurations recorded in real battles within these trophy bounds. Snapshot data is computed from battle logs retrieved via the official Supercell API and refreshed every 30 minutes. Win rate represents the percentage of battles won when using that exact 8-card deck configuration across all battles tracked within this arena's trophy band. Curated guides are provided for arenas 1–28; arenas 29 and above use snapshot data only. All deck performance figures are filtered by a minimum battle count to ensure statistical reliability — low-sample configurations are excluded. Trophy ranges are fixed per arena: Arena 15 covers 5,000 to 5,500 trophies. Data from the official Supercell API is the sole source for all performance statistics shown here.
