The sakura packs are really good, they are great for collecting those 3* cards for your collection.
1st pack was Seria(2nd copy), Chamail(4th), and a couple of random low rarities I had.
2nd Glosfiea (2nd copy), didn't get another 3* but got my 3rd Rapid Growth.
3rd Femiel (4th copy), Urgrant (4th copy) so this was my only bad pack, but I got a 75% refund so it wasn't bad.
4th Riza (4th copy), Sheer winds (3rd copy)
5th Aquamantic Bubbles (2nd copy), some other 3* (4th)
6th Gravan (2nd copy), Mordmarc (4th)
7th Safira (3rd copy), Al Tauc (1st copy)
