Hello!
First of all, I've been working on a new item guide. It's not finished yet but it does have all the MT/TT sets with the preview images - as well as links to the original announcement to see the details of the items - so maybe it helps you a bit

Also.
I have the Ocenia set (Black, Blue White, Ginger, Violet), the Skydancer set, the Saraswati set and the Apollo set.
I would take 4 FCs per set, that's the price I'm selling most of my old sets nowadays.
But I would love to trade for other items, if you can offer any. I'm mostly looking for stuff from 2017 to 2021.
