How to Change Members in Clan War Leagues (CWL) & Safeguard High-Tier Base Transfers

To change members in Clash of Clans Clan War Leagues, you must be a Clan Leader or Co-Leader. Open the current CWL War Map during the active Preparation Day, tap the blue 'Change Members' button at the bottom left, deselect inactive accounts, and select replacements from your registered 50-player master roster. Crucial rule: If a member was excluded from the master roster when your clan initially spun for CWL matchmaking, they cannot be substituted in under any circumstances. While managing elite competitive rosters across mobile games, institutional security remains paramount. If your clan also fields top-tier squads across multiple titles, you can Browse PUBG Mobile Verified IDs or inspect our Browse [8 Ball Pool IDs](/store?game=8BALL) inventory for verified multi-game profiles.

Trading high-level Town Hall 15, 16, or 17 competitive CWL bases peer-to-peer on Discord, WhatsApp, or Telegram presents an extreme hazard. Rogue sellers routinely exploit Supercell Support tickets or automated SMS recovery to pull back accounts days after accepting payment. At 217 GG, our escrow protocol mandates a 3-point security lockdown: 1) Executing an official Supercell ID email transfer to the buyer's dedicated mailbox, 2) Generating new Supercell ID Account Protection recovery codes directly on the buyer's secured device, and 3) Removing legacy mobile phone numbers and logging out all concurrent sessions. Read our full protocol in the Safe Escrow Guide to verify how funds stay protected until complete transfer validation.
