This means when you donate one RARE card towards another player’s request, you can request donations for that same card afterwards. If you want, you can use gems to open up the chests early. You can get about 80 Gold from every free chest, this means you can get about Gold every day from opening Free Chest 2 in the morning and 2 before sleeping. But I did this to prove a point. There are a few simple ways for making some quick Gold and saving up for new cards to add to your collection and upgrades. Now, I do wonder how many other players are like me.
