Im not good at rating things so cant help much there. I can tell you what I had to offer to finally get my sparrow hat. I gave 5 star snowman, 5 start bat, 5 star fireworks, 5 star teleport and 5 star invisible.
I think I paid way too much but after months of offering I got no takers until I saw someone want magic for the hat at another board. I wanted the hat a lot for a friend of mine on VMK because thats the only thing she wanted so to me it was worth all that magic.
Anyway here is a bump for you and a good luck!!
