On the subject of confirms:
Nice way of punishing Yu's DP (safest when he whiffs or has no meter) is to do 5B CH > OS Maragi D > Maragi loop (omit the first 5C on first explosion to get 5BB > B Agi ender). As long as he is not too high up this always combos since 5B should CH as he is falling from the DP.
I call it OS Maragi D since you can input 5B and then cancel Maragi D like normal. If 5B connects Maragi D comes out, if 5B misses then Maragi D never comes out (if I tested this correctly).
