http://harlequinraven.wikidot.com/ has my current wishlist, IOU policy, and what I can offer.
I will only take IOUs from people I feel comfortable doing so. If you have references, I'd love to know about them, especially if you are trading me something harder to get (such as CB metals).
I am very serious about honouring my own IOUs, and if my dragons are being stupid about producing them, I'll usually trade for the right outcome in order to get you what you want ASAP. For this reason, I'd really like to see your exact lineage so I can make sure I don't trade for a related one. You can see my own fulfilled past IOUs on my above link.
THINGS I ALWAYS WANT (As long as the value equals what I am offering)
CB or purebred Undine hatchies
CB male Autumns or 3-5 day eggs
2nd gen Thuweds
Spriter alt base dragons (the lower gen the better)
