Exchange of letters in Clash Royale
The card exchanges in Clash Royale have always existed, before you could trade cards with your clan members using exchange or exchange tokens.
As we well know, the cards that exist are: Common, epics, discounts, and legendary; each one had an equivalent exchange token that allowed the cards to be exchanged fairly easily.
Since last year, almost towards the end of it, things became a little easier when it came to exchanging cards, as a new feature took place in the game: The Merchant of Rio de Clash Royale.
You must continue using exchange tokens, but they will not be made with your Clan members, the merchant makes the exchange of cards possible, and that it is much easier.
The cards available to the Rio merchant change continuously, each time midnight arrives.; For the exchange to take place, you will have to offer him the exchange tokens, and he will give you three random cards from which you must choose the one of your choice.
In case you don't want to wait until midnight, you can always give the merchant some gems to offer you new cards, but I would think so.
