Like most Magic: The Gathering cards, the value of Bitterthorn, Nissa's Animus depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Secrets of Strixhaven Commander)
Its just a shame the character of the set makes it feel so gimmicky
Grixis Vampires Evelyn the Covetous may be the headliner here, but the core of Bloodthirsty Adversary, Bloodtithe Harvester, and Corpse Appraiser each provide a ton of value in efficient threats

As in, many of the uncommons are of the caliber of the rares of many other sets
Now that Chord is a core set rare, that price is going to get absolutely crushed
