If I am not mistaken, yes that is real. Unfortunately, that is from the xy evolutions expansion, which is relatively new and not very old. Don't be disappointed tho on amazon it's $70 if it's a holo, which I belive yours is.(idk hoe true this is, but I know it costs some)It's pretty good, but it's not like those ones from the very first expansions that cost much over $100 tho lol.(about $1300 ) (And uh sorry if you don't live in america, use a currency calc to find the approximate cost for u)(I should also note that I may or may not be correct, but it appears real. If it came out of a booster, it's real. If it came from a friend, it depends how reliable they are. If it's from some random place on ebay, you may want to go to other sites where there are many more Pokemon collectors who have tips on identifying fake cards)
Hope I helped!
