Loved it. It's an easy A for me as well.
*Snips and Snails comment about preferring Trixie when she was a fraud (that had me rolling).
*Twilight standing on water, levitating water spheres while Zecora balanced on a staff. Come ON that was awesome!
*Fluttershy. All of her appearances this episode were awesome.
*Breaking the 4th wall at the very end. Epic!
Also, "Saddle Arabia"!
