if you want the art to a games publication line, you have some research ahead of you,
your best bet is to first find a repository of all the rulebooks , including those of the card games and such,
and go to the art credits , note down all the names .
then go search these names on google or directly on sites as deviantart , artstation, pinterest even the loathed tumblr.
Theres probably more too , anyway you are looking for sites that allow the artist to advertise his work to potential publishers,
and then its just a handy pin or copy paste to your slideshow folder away.
