The only part of Draciel V2 that would be worth using in a tournament is the SP. If they're fake, they will almost certainly break after a couple of matches, because real ones are extremely breakage prone anyway. Honestly, Fin Tectors are pretty lame, they really just add a load of recoil.
And if you're looking at using the AR, don't sell that darned griffolyon man, it was one of the best beys in that lot!
If you're looking at using the base, you'll lose every single match anyway so it's no big deal being DQ'd.
I doubt you could be disqualified for it because it's impossible to determine that it is fake. Morally, I wouldn't use it if I wasn't sure that it was real, but honestly, I just wouldn't use it because it's parts aren't useful.
