I've pulled several, and I'm fully willing to admit I sold my future firstborn's soul to the devil as payment for the luck.

I pulled Alpinia and Christmas Rose on my first 50FG gacha pull on my first day, eventually decided to open an alt account a month later for the new Sakura starter deal and to kill extra time, and that account rolled an Alpinia on it's first 50FG roll after I got Sakura, making 2/2 6 Stars on day 1.

I've since rolled my Ardisia on the Step Up stage 2 gacha last week, before I got my Daisy with my ticket. I do throw some money at the game for my main account, but I have yet to spend anything on my alt since the day one purchase. I was considering picking up the Easter ticket on that account but eh. I've yet to pull a 5FG 6 Star so I think I might start spending my alt's FGs on YOLO pulls to get my first 6 Star pull like that under my belt.
