Just like @Ratequaza, I have my doubts. Russian cards started during the XY era, so it’s very strange to see a Russian card from the very first BW set. If it were one of the last BW era sets, it might have been somewhat plausible.
And although it’s a test print, and I see an OPTION 2 in the bottom-left card border, there seem to be a bit too many differences with the actual released cards in terms of layout. 
If we put the scan without physical copy of Ratequaza’s post, next to your card, and next to a card from the first actually released Russian set (XY Kalos Starter Set):
We see that the online scan and actual physical card both lacked a Pokémon flavor-text, unlike that test print (or this card in other languages).
There are also a few differences in font-size, like in the texts below the artwork for example. Or the bold Weakness, Resistance, Retreat Costs, and Illus. Kagemaru Himeno at the bottom, which aren’t bold in the online/physical cards.
But one more telling thing, which wouldn’t just change due to a potential test of card layouts, are the differences in the translations of:
- The ‘Basic’ in the top-left
- The ‘HP’ in the top-right
- The ‘Retreat Cost’ at the bottom
- The second ‘Vine Whip’ attack
- And the ‘Grass Snake Pokémon’ below the artwork
Which I’ve also seen pretty often with fake Spanish cards, which were manually translated from existing English cards, before the actual release of the Spanish set. (Here an example of one - the smaller card on the left is fake.)
And tbh, the borders also look a bit sus on first glance, although it might just be the pictures.
So yeah, very cool if it’s an actual Russian test print of some kind, but at this point, I think it’s simply a clever fake.. But I’ve been wrong before about a test print that looked fake, so 
(Or vice versa with the Japanese prototype scandal..)
Either way, thanks for sharing. Just in case, I’d love to see more pictures of it, including close-ups, if possible.

With “Functional language” (English, Spanish, French, German, Italian, Portuguese & Russian) I mean, languages that have card assets in that specific language. There were other languages such as Swedish or Finnish that only have card assets in English. In fact, Russian only had Card Assets translated in BW & XY eras. HGSS era is untranslated (assets in English)
