Saving up currency for Shop > Workshop

Around Arena 3-4, you'll have enough currency saved up to get a guaranteed Legendary card from the Shop > Workshop. After getting one Legendary card and adding it to my deck along with another high-tier card obtained from quests, things have been going so smoothly it's almost disappointing lololol I was complaining about lacking gold, but then there are events like splitting 20,000 coins among winners for 5 consecutive wins / a daily quest worth 5,000 coins / logging into the LUDUS site shop for 500 coins daily, etc. As you climb the Arena, more gold sources appear. Good luck to those doing hidden quests!
