Yup, those are from a mobile card game. Much like how some of those like Monarchs (some of them) come from a DeviantArts Artist's and a couple of mines as well.

For anything, you can pretty much type up whatever it is you have in mind that you want to get (ex. Want to find some really cool art of armored characters, just type in "Armored knights" or something along those lines on google and they should give you plenty of them to look and/or choose from).
