Game cards

Just recieved a bunch of cards from my cousins in the UK, who've outgrown them, and now their mum's sent them to me. Problem is, I don't collect cards, so where in Hong Kong do I sell them?
Got a bunch of "Match Attax" football trading cards, and also some Lego cards, "Ninja" cards, and 'Chima' cards.
I'm not looking to make too much money, but hopefully I can find a place to offload them.
