As seen in recent Magic: The Gathering set releases, Wizards of the Coast has made an effort to increase the playability of Commons and Uncommons. Making Commons and Uncommons more playable can lead to a better gameplay experience in Limited and more lower rarity cards found in Constructed decklists. As a result, average market prices of several lower rarity MTG cards printed in the last few years have exceeded many Rares and even Mythic Rare cards, especially their foil counterparts.
In my TCGplayer Infinite article, 7 Crazy Valuable Foil MTG Cards You Probably Own, I highlight a handful of Common and Uncommon foils with considerable value. You may want to check bulk boxes to see if you have foil versions of Tamiyo's Safekeeping, Stroke of Midnight, and other in-demand Commons and Uncommons in your collection.
