Hello to everyone!

I need some help (I sorry but Im really bad in my choices xD)

I want to use my 6s ticket, but I dont know what can be the best choice:
My 6s FKG are these:

Slice:
Black Baccara and Fritillaria

Hit:
Cherry, Dendrobium, Christmas Rose and Alstroe Maria xD

Piece:
Daisy

Magic:
Sakura, Ardisia and Lycoris

This and the last years Im really unlucky in my tries with the Gacha Machines and I need some help for the best choice with the ticket.
Mei Plumblossom, Anemone, Ionocidium, Burning Bush, Saffron, Snowdrop and Hollyhock, in other words who can be the best choice for 6s FKG with the Piece class (I think is my weakest class), and I think that can be important that the Girl will be a Bloomable unit.

And Im really sorry with my english!! xDDD I dont have any issue reading, but writing.... xDD
