I pulled Mana Echoes a few years ago. It sat in my binder, I had no idea what to do with it. I didn't want to build goblins, I wanted to make a machine. Then I started adding cards, helped with deckbuilding videos by Salubrius Snail, and ended up with Rith, the Awakener. A token deck which denies the typical go wide and cast Craterhoof, it uses tokens for mana and draw and fodder for big devour creatures. Lots of tweaking ensued. What started as a tokens good stuff deck turned into something fun and creative. I highly suggest trying to build a deck around your favorite card. Say no to the common themes and best cards available and try to distill an idea to its maximum. I love deckbuilding this way and can't wait to try it with something else. Let me know what you guys think and if you have any suggestions! Find the decklist here: https://archidekt.com/decks/21806945/rith_devour
