Can you explain how trading works in Clash Royale?

In Clash Royale, trading works by allowing players to exchange cards with one another through their clan. To initiate a trade, a player needs to have a trade token of the appropriate rarity—Common, Rare, Epic, or Legendary—which they can obtain from clan wars, special events or purchase from the in-game shop. Once they have a token, they can post a trade offer to their clan's chat, specifying the card they are willing to give away and the card they would like to receive. Another clan member who is interested in the offer and has the requested card can accept the trade by using their own trade token of matching rarity. This system promotes strategic collaboration within clans and enables players to collect specific cards they need for their decks more efficiently while helping others get rid of surplus cards that might be more useful elsewhere.
