This is tough, the whole set is to die for!
In the end I voted for Yum Yum and Nightglider. Yum Yum is super high on my wishlist, and Nightglider (who I do have, luckily!) is just too gorgeous not to vote for.
However, if I could pick three ponies I would have voted for Merriweather too. She's super pretty, and it she brings back sweet memories! Years ago when my husband and I weren't living together yet, I spent the night there. That night I had a pony dream. You know, the type of dream we all have, where you are at a fleamarket with ponies everywhere.
I usually only get those dreams when there's a reason for it, like Kingsday coming up, or when I expect a pony in the mail. That night there was no reason at all, strangely enough. But the next day we went to the mall, and you won't believe it, there was a fleamarket we didn't know about... And there was Merriweather sitting on a table!
There was also a G1 book from the same seller. My pony radar is never off!
