Back in the dayyyy, like primary school days, trading Pokémon cards was quite a big thing!
I used to over exaggerate the value of a card I had in order to get another card that was waayyy better…
I cannot remember what I traded (probably a full art Zekrom since I no longer have it), but I know that I received a mewtwo (which looked battered cause the previous owner said he unknowingly put it in the washing machine with his trousers
)
It may have been an L on my part (cause the Zekrom card looked niiiiiice), but all I know is that I was the only kid with a Mewtwo in my school…
I still have it now and idk whether its a fake or if it is really rare cause I googled pics of Mewtwo cards and I am yet to see this particular design…
Edit 1: Ok after some more searches, I’ve found the card… I’m convinced that it is real, but not 100% sure on how rare it actually is 
Edit 2: For those of you who are wondering, this is the card I have, but imagine it with a considerable amount of rips and tears (you can still see the stats on the card, it just looks battle tested)
