Heh - I just read this article and became reminded of my idea: https://keithburgun.net/three-types-...-one-good-one/

Going by the definitions used in that article, in the core form, this would definitely be input randomness. But probably variable rather than uniform... unless you didn't return cards to the draw deck until you'd run through said deck. Not sure that that would add enough to be worth the clunky mechanic, though.
