That was my post, you can find it on page 3 or 4 on this thread. And I already tried that out, it worked for me twice :P. First time I did around 6 times in normal gacha and got a 5* (ampys), then I turned back to 11x premium roll, got Black Baccara and Camelia. Second time in about a month later, I rolled 16 times in normal until I got a 4*, then did 11x roll, got Cactace and Lily Rubellum :P
