I bought 150 sacred crystals when I first started this account the other day. After spending a handful for barracks decided to spend most of the rest on premium summons. Got my Sophie, Elizabeth, Sabinne, Flamel, and BOTH plat princesses, Lilia and Sherry. Among some gold units that sound to be pretty good according to other players (one is Mehlis, which I hear is a good source of magic damage even late game). I've been running with the twin Princesses (as I've taken to calling them) almost constantly on the desert maps, with Flamel acting as the healer for the two. Wish I had more Flamel in my line up; seriously, she's stronger than both Robert and Iris (my other two healers) with the same level and affection.

I also pulled Misha earlier, who I've read is a pretty strong Lancer for being a silver.
