So a few stuff snatched on my end.
Spoiler: Battle Card Dungeon has a chance of dropping Collab cards. Old info, but it really surprised me (click to see content)
Spoiler: The new Combine feature also drops 5* Universal SP cards. Chance rate must be very low too but it's possible. (click to see content)
And now some news.
So the recent polls have ended and to no one's surprise, Mai is getting her FES version, even tho she should have gotten one by now. What's really surprising is despite the high demand for a FES King, she did not get that much support compared to Athena who got more than twice the amount, oof.
Regardless, it's safe to assume all three will get their FES class with Mai arriving first.
The other poll on who needs to get the Goenitz treatment has concluded with Orochi and NESTS-style Kyo leading the ranks with Original Zero being next. Worth pointing out Orochi has a 3PG SP Card so expect fun times. Orochi Yashiro will probably get his buffs by the time KOFXVI arrives.
There is also the launch of a "Carnival" rally which gives you various rewards based on Battle Cards acquired. For this event, the amount of AP is reduced in the Battle Card Dungeon. The last reward is a Imprint Stone Mystery Box, but it's not worth burning AP and rubies for IMO.
