I have also written out this information for quick referencing and should Youtube not work.

Basics First
His two most damaging combo strings are:
In Your Dreams - ( 
+ 1, 2, :u: + 1 )
and
Playing With Power - ( :f: + 4, 2, 1 )
In Your Dreams is a launcher that can then be used to juggle for big damage, faster start-up than **Playing With Power **and much more useful to start off a big combo.
**Playing With Power **into X-Ray deals 48%.
For low combo strings that can then be cancelled,
Ungrateful Piggy - ( + 3, 3 )
can be cancelled on the first hit into **Hell Spike Close **( :qcb: + 1 ) for a decent launcher.
Overhead,
I Love Screamers - ( + 2, 4 )
can also be cancelled on the first hit into Hell Spike Close ( :qcb: + 1 ).
His overhead also causes a ground bounce into juggle state when used in an air combo.

Most of Freddy’s B’n’B’s start with In Your Dreams launcher:

Will be updated with more info ASAP. For parts I have left out (E.G. Damage) or if something simply doesn’t work. OR If you have even found better combos, just let me know and I shall add it here.
