Ooh that's new, the Sapling Raising event. I'm not entirely sure what it's about, but I'm excited to play it once it comes out again. I'm also kinda disappointed they aren't doing Level-Up Boss events anymore. I only got a chance to play 2 of them and both times I was pretty new and too weak to really do anything. It seems like it'd be pretty fun, if I'm remembering them correctly.

Oh and I totally agree with the Card Flip Event being annoying since it has so much near-useless stuff like Nazuna's Cake (sorry, Nazuna). 100%-ing that event actually seems like a waste of stamina.
