How can I tell authentic Gem 2 cards from fake ones?

Question

Im interested in the Gem 2 set, but I’m afraid of buying as I don’t know any details of what the fakes look like vs real ones. So I’d like a comprehensive list of the real vs fake cards for the Gem 2 set.

Thanks

apparently there is an anti-tamper marker ( the pokemon logo ) in the bottom corner of the cards... im ngl i cannot see it in pics though ;(
