Have them printed from a service. A normal deck of cards should run about $30 USD. The paper, laminate, ink and maybe sleeves will probably cost the same or more and will come out with way lower quality especially if this is your first time crafting them.
I’ve done both and unless you want really quick and dirty prototype cards or something that is super handmade that you drew on yourself instead of designed on a computer, the ones from a printing service win hands down.
