I have a fantastic combo-ender to contribute.
Ending any aerial juggle off of a walbounce with B1, 2, 1, cancelled into gunshot special move, then into silly slide, then tantrum stance is a fantastic setup to nearly guarantee more damage against opponents who wakeup poorly.
You can also furtherThe initial hit of the tantrum stance lands almost perfectly, at the exact moment at which the opponent becomes strikable. You may find yourself stuffing many wake-up options with this,
You can also further confuse the opponent by leaving out the final, combo ending gunshot, drastically changing the time at which the opponent lands on the ground.
Doing this after first landing my previous BnB ender will confuse the opponent-- causing them to mess up their wakeup attacks, as they weren't expecting the combo to "drop."
This opens them up for even more awesome stuff.....
