Personally, I'm a big fan of Obsidian Flames and Twilight Masquerade, while base Scarlet & Violet's Gardevoir ex #245 Special Illustration Rare is arguably one of my favorites of the entire era
Flayer of the Hatebound is one of them, and was an inspired choice for the deck
Now that we get to play with this card in Timeless, we can see how it works in high-powered formats, where making a Food and then turning that into an elk is a shockingly common pattern
Thats why Wizards has generally steered away from it in modern sets
Triumphant Light introduced the Trainers Irida and Adaman healing Water-types and mitigating damage for Metal-types, respectively which both still hold value
Otherwise, this is in the running for the least wanted card in Pioneer Masters on Arena
