If you’re building a Commander deck in Magic: The Gathering, there are a few hard and fast rules you need to follow as you assemble your 100-card battle plan: roughly 36-40 lands, about a dozen removal spells or other ways to interact with your opponents, a few boardwipes in case things really get out of hand, and one Sol Ring. Virtually every single Commander deck in existence benefits from Sol Ring, one of the most overpowered, totally busted cards in all of Magic‘s 33-year history.
