Worse, why would anyone use an uncustomized Driger F for a match? I mean, other than because they like the blade or something.
Eitherways, being able to beat a certain HMS blade or not with a plastic gen one isn't what makes it unfair/not. Now, HMS has the advantage since they're overall better, which doesn't mean X HMS combo doesn't get beaten by X plastic combo in the right circumstances, but yeah, most simply perform better.
Of course if you were entering a tourney where both gens are allowed, it'd be pretty stupid not to use HMS, unless you come up with a plastic combo that out-performs most comon HMS ones as well as being able to beat those depending on stadium, which if so, do tell us (good luck at finding one).
What I think should happen in tourneys if possible, is having a separate one, just for plastics as some have mentioned, so they can actually get some use, since anyone with half a brain would stick with HMS for the main "everything goes tourney". You know, kinda like in Pokémon, where we have tiers based in usage and power. If everything was allowed, it'd be Ubers all over the place and no one would even use stuff like Mence or Garchomp (which are top tier OU) when they have Rayquaza and Groudon, much less most UU Pokémon. In OU, Ubers are banned, but everyone else from OU and the tiers bellow (UU/NU) is allowed. So, lets say the plastic tourney=UU, while HMS are OU, thus aren't allowed for that tourney, etc.
I mean, unless everyone in the tourney doesn't give a carp about plastics anymore.
