Gambit's Monstrous Combo:

To get a huge combo with Gambit, you must
first have your super bar at level 3, and
of course be playing as Gambit. Then, do 
Gambit's Royal Flush super. If it connects,
cancel it after at least the 33rd hit while
the super is still going on with a second 
Royal Flush. Then, when the combo counter 
reads at least 62, cancel the second Royal
Flush while it is still going on with a
third Royal Flush. You will have 99+ hits!
(Although the combo counter stops at 99). 
This will work only if the opponent is 
standing on the ground. If he/she is 
slightly in the air, the cards Gambit throws
will not hit the opponent as much times.
