Yeah, it works. I'd suggest coming up with maybe another for Dynasmon perhaps? I mean, some variety in final stage, yes? Just a suggestion. Also, unrelated, but question marks look weird in the reply box font.

Anyway, Silent Symphony... sounds like it'd be a spell that renders foes mute, or makes a sound so loud that they can't hear afterwards. I do like your Dynast Bullet, it's a nice addition with this Digimon's Combat style. I'm always one to advocate barriers in this RP, however.

Slightly related- I'm compiling as many sprites (Battle Spirit Style for now) as I can to make a full list of the team in every form. I may make custom sprites of ones that don't fit the scale entirely, or I might make sheets of some of them... maybe make a sprite comic of this when it's done, who knows. Also made a correct looking-the-other-way sprite for Omnimon, since, you know, two different arms.
