Please list the submissions that occur in BJJ tourneys (obviously excluding the gi based subs) that do not occur in MMA.
I can list a few for you that ARE pulled off in MMA:
Guillotine
Rear naked choke
Americana
Anaconda
Kimura
Triangle
Googoplata
Triangle/Arm bar combo
Straight arm bar
Umoplata/ankle lock combo
Knee bar
Heel hook
Head and arm choke
Achilles lock
Figure 4 foot lock
North South choke
Hmmm... seems like more than five or six.
Now which were the ones that are done in tourneys that are not done in MMA?
Probably the only two subs that have not been pulled off yet are the Darce and the Von Flu... and that is probably just because they are not that well known yet.
