I was looking at some stuff in training mode, and I saw that 2C can kind of work like a.bufu, except in the corner. Midscreen, we may opt for maragi ender > 5A > a.bufu reset, but in the corner, we can do Sb.Zio ender > 5A > 2C. On backwards, neutral, and upwards air tech, I've gotten this to work, but not on forward air tech; the CPU ends up IBing. Maybe we could do a FC grab (air grab, even?) here, since the grab is only 5 frames, and I doubt someone would expect it after falling from a blocked 2C.
I'm aware that on air tech, some characters have options, and maybe they'll be able to beat this. However, I feel this is the same (or similar to) the b.bufu > 2C midscreen reset.
Edit: If they don't tech, and the 2C becomes a yellow beat, you can always get a free maragi oki.
