I believe I won a couple of fights on the 4th turn yesterday, but I didn't get to screenshot any until today.
By the way, I've spent a few flower stones just to make up for the raid points that I can't regenerate while I'm out at work.
I've won about 4-5 times for every 6 fights, with an occasional draw or a rare loss due to really bad RNG in support phase (thanks to Nazuna's attack which barely makes a dent on anything!)
If you're referring to the promo itself (not the ticket), it only lasted until yesterday (2/19). On the other hand, the ticket from that promo doesn't expire.
