What I have:

Aurleon Haunting Spirit x2
Draeyl (aged) Shimmering Shard
Draeyl Chilly Dawn x2
Faelora Ripe Plum x3
Luffox Enchanted Lake
Lunemara Carved Pumpkin x2
Morkko Vampiric
Zolnixi Dusky Dawn

What I want:

15'000g for any single catalyst
Trade any regular catalyst for any other regular catalyst

What I mean by "any catalyst" is that even a catalyst I already have can be traded, I don't actually want any catalysts. Any catalysts that are traded to me will then be added to the above list of catalysts I have available for trade or sale.

If someone wants to trade their fabled catalyst for some reason, then they will get to pick up to 4 regular catalysts.
