Nobody wants to say it, but First Chapter slab liquidity isn't a market problem. It's an art problem.
Chapter 1 Enchanteds look like Epics do now. Recolored background, same frame, that was the ceiling of the set.
Fabled reset the bar. Full-bleed Iconics with lore star foil and 3D hot stamping, and Enchanteds that actually look like chase cards. Winterspell followed with a new Enchanted foil pattern on top of it.
Winterspell slabs move because people want them on the wall.
First Chapter slabs move when someone needs to check a box.
Nostalgia isn't a treatment.
