Someone (Gliscor) actually asked me this once, since I can read a smattering of Japanese when it comes to translating things.Shun said:Is Virbank City Gym translation correct? I mean, on Bulbapedia and Serebii it's translated as "Put 2 dmg counters instead of 1" and this really matters in poison decks.
I personally have come to the conclusion that it's "2 more", not "2 instead of 1". The reason for this is I looked at the translation for Crobat Prime, and the wording on that card was different than the Virbank Gym. (I just looked at the Muk from NXD right now and it's got basically the same wording as Crobat.) There's an extra word or two on the Stadium that aren't present on Crobat or Muk.
So yeah. I would say "2 instead of 1" is incorrect, but I am not a Japanese buff, so do not take my word as absolute truth.
