this may be new, and fairly useless, but new...maybe
its possible to get a psuedo summon for the sake of organization
what you do: while falling, attempt to summon a pool ball extremely close to the ground (note, timing seems REALLY tight, like you have to be doing it right as you're landing, and you may even have to be special cancelling something, I haven't really been able to hit it off a normal jump, just a falling j.s or j.h)
what you get: the pool ball doesn't come out, but those that have already been summon move as if you made that ball summon (as in if you did j.214K the k ball wouldn't come out, and vemon doesn't really make any indication of having done the move, but the other balls move into K formation)
theres somewhat of a use for this, just being sneaky really, but in this particular set-up:
(opponent on ground) x > 5S (3) > 6P > 6H > 214S > 6H > 623K (s ball tele) air dash > j.S > j.H > delay j.214K*** to right before you hit the ground, what this will do is kinda stealth pull the s ball you summoned earlier below and behind the opponent while the k ball doesn't come out. The s ball is easy to miss moving here, and if you pushed them to the corner (the combo goes over 1/3rd the screen) you can then do blockstrings into teleport to get an instant overhead effect (without the k ball giving away your potential teleport locations) as you'll be teleporting on their head basically (and allows for combos like 5H > 623K > j.H > 5H > 623K > j.H > 5H...)
