I'm gunning for Ominous Latin Chanting.

Sort of something you'd here in the dungeons of a castle of the catacombs of a cathedral.

We wont get any new sounds from the faceplates, there are only the four (gaim, baron, ryugen, and bravo) so Im guessing the one that looks like Gaim, will have type 1, and barons will have type 3. Could be wrong, Id like to see someone else use Ryugens sound.

Maybe ominous Latin has yet to be unlocked?

There's a series of 2 buttons on the Sengoku Driver that the faceplates press down on. So since ther's only 4 combinations, no ominous latin. But I would love the Lockseeds to do that.

Im pretty sure everyone has hacked the buttons enough where the plates go, nothin new has happened-

type 1 plate- (Gaim, zangetsu, kurokage)no notces so deafult sounds (also why genesis core works as gaim)
type 2 plate- (ryugen)- uses the top notch

type 3 plate- (baron, gridon)uses the bottom notch

type 4 plate- (bravo, knuckle)uses both notches and last possible sound combo

Then how does the adapter work?

There's a little button that raises when the Blade slashes, which hits some stuff in the Core, Salad attachment which activates the lockseed.

I am not really sure, but I think there is a middle piece that it has to fit on, to use the part where you open the energy seeds.

I wouldn't put it past them to release a new driver based on Sengoku for these seeds. Sort of a White Wizardriver/Giga Gaburevolver deal.

Depending on how the story for Gaim the show goes, we might get a 3rd type of Driver.
