Aww, you need to already have one from the set... I'd be all up for both starting and completing the second set of Pony Friends.
If it can be considered a 'set' I'd love to complete the G4 Crystal Empire collection. The only packs that didn't come to Australia were my favourites out of the whole line. Glimmer Wings Diamond Rose & Pinkie Pie and Sweetsong & Fluttershy, and the Princess Ponies collection with Celestia, Luna and Cadence.
