If you build more than one deck (or you’re updating a Cube), the real cost isn’t just money — it’s the constant “Where did my Rhystic Study go?” scavenger hunt. The fastest way to get out of that loop is to proxy a reusable staples pool: cards that slot into a ton of decks, stay strong across metas, and remove friction every time you brew.
Here are 20 that give you the most “I can build anything now” value.
