As the new version of the legend of the hearth legend near the witch forest, Blizzard made a live broadcast on twitch, and Ben Brode introduced many exciting new cards and other new versions, but the most interesting content revealed during the live broadcast was a new function of the "loan card group". If you're fighting someone, you're not familiar with the game, and you don't have many cards in your hand, or if you just want to help people test the card group, you can use the "loan card group". The player you borrow will pop up a dialog box, and then you can use someone else's card group, but that's the work. It can be used only in the 1V1 friendly match. In the next version, you can exchange cards with friends to learn skills. For many players, this is also a very convenient function. Many hearth players are appealing to others to share this function with the others. This borrowing function satisfies the needs of the players.
