On a fairly humorous note, but still serious, I've had some results by randomly finding time to throw out a bowling ball when a Ragna is backpedaling and feeling me out(and out of range). More than half the time it will connect from setups, but more often than not just serves as a way to get him to jump/"Oh god do I seriously need to block that?", but really just confuses them. When it does actually connect, if I'm close enough I can get a free C poke in, which may or may not be in part to minor online delay. Not gutsy enough to try anything afterwards, but still funny to throw them off for a bit.
