I wanted to ask, because I think I try too hard at this kind of thing, but what do you think about this FC setup from oki?
Starter > Sweep > 5D > Dash > Back Dash > Raging Lion B > (5DD) > Whatever combo works from FC Lion
The idea is to get the opponent to think they're safe from Yu following up to where they attempt to attack Izanagi, in the process getting hit by Lion B. If they block it, 5DD can be used to keep the attack safe. The dash > back dash is obviously an eye trick, but it also helps with timing for the setup.
