Hey sidon! I feel sorry that you’re feeling that way. I haven’t traded UCs very recently but I was stuck with a DN faerie Peo for months before in the past and I couldn’t even trade laterally. In the end, I UFAed the pet XD out of frustration. Please don’t feel bad for offering on pets of the same tier! We get ignored or get rude responses some times but it’s totally part of PC trading! Seriously, just offer them on so long it’s not an outrageous under-offer. I think faerie Ixi is the popular one within T5 among faeries and faerie shoyru can be popular sometimes. I personally love faerie blumaroo but I’m not sure how they trade.
If you don’t dislike the pet too much and have a little budget to spare, maybe buy another pet that’s more tradable in the ck forum and keep this t5 faerie for yourself.
