Kingdom Hearts Cards?

So my sister @heyysacha walks in and asks me if I want something. I say lol sure bitch, and then she hands me these

This is the Kingdom Hearts Trading Card Game friends. No I don’t know either.

Like I have no clue how this is played or set up or anything. There’s the player, friends, keyblades, worlds, enemies, and maybe more idk.

If anyone knows anything (or hell is even interested in having these) lemme know!
