I'd be totally fine trading that Merham. c: Yep yep.
As for the Decayed Fenling, admittedly no, I don't have an idea for it. uwu I may get one one day, or I may not. I just like collecting the Seasonals; I've been assigning characters to them and I just love using them. And I can't help but love the new Fenling lines. xD
So I mean, if that's the deciding factor, I can't change anything about that. uwu But I'm good for the Kuhna + Swift for the Merham. I do much prefer the Swift over the Decayed. c: If I have to cut my losses.
