This year has breathed new life back into several M21 cards.
Multiple Magic: The Gathering cards from Core Set 2021 have maintained and increased their value over time, from booster fun variations to regular versions.
Released on July 3, 2020, Core Set 2021 contained a total of 278 regular cards. Cycles within the set included Shrines and tribal lords, along with five planeswalkers. Upon rotating out of the Standard format, several M21 cards increased in value due to gameplay in formats like Pioneer, Commander, and Modern. Booster fun variations within the MTG set included extended art, borderless, and Showcase.
Terror of the Peaks found a home in the Standard format via 4C Omnath and continues to get played in the Commander format. The dragon dominates the M21 cards worth money, having an extended-art foil version that is valued at around $82. The non-foil extended version is worth around $45, along with the prerelease foil promo version. And the regular Terror of the Peaks card is priced at around $22.
Printed in Fate Reforged, War of the Spark Masterpieces, and M21, Ugin, the Spirit Dragon remains a valuable MTG legendary planeswalker. The dragon’s WAR Masterpieces extended art is valued at over $100 at around $114, while the M21 foil extended-art version is worth around $65. Ugin’s Showcase version is worth around $48 and the prerelease foil promo is priced at $40. The regular version of Ugin, the Spirit Dragon is valued at around $23.
Chromatic Orrery was a suspected sleeper within the M21 set. As a colorless Artifact that has a CMC of seven, it can add mana of any color once on the battlefield. And for an additional mana ability, it can draw a card for each color among permanents that the player controls.
The extended-art foil version of Chromatic Orrery is valued at around $50. Other booster fun variations, including the prerelease foil promo, are worth between $25 and $30. The regular version of Chromatic Orrery is priced at around $20.
Hanging onto its value due to play in Commander, Fiery Emancipation is an Enchantment that deals triple the amount of damage from a source you control that dealt the damage in the first place. The extended-art version is worth around $46. Other variations of Fiery Emancipation are valued between $25 and $30. And the M21 regular Fiery Emancipation version is worth around $22.

Elder Gargaroth clawed its way out of the bottom rankings, once having its regular version valued below $10. The beast creature has an extended-art foil version priced at around $30. Other variations are priced between $15 and $20, and the regular version of Elder Gargaroth is worth around $14.
