Town Hall 3+ players collect troop cards from battles and events, trade duplicate cards with online Clanmates, and complete sets for permanent and progression rewards.
Supercell says two battle card packs can be earned per day, ten are available when the event begins, and up to 68 cards can come from battles during the event. Tutorial, Supercell Store, Trader, medal-event, and social drops add other opportunities. Duplicate cards can be traded in Clan Chat or exchanged for random packs. At launch both Clanmates must be online to finish a trade.
Set rewards include Runes and a Legendary Chest. Collection milestones include ore, Builder Potions, the Book of Cards decoration, and the Manga Fury Prince skin. Confirm the live collection screen before spending duplicates.
Available at Town Hall 3 and above. Supercell published an August 1–31 date range but no start or end clock. Reward claiming and trading close September 2 at 08:00 UTC.
