In general if you want cheap trading cards, look for games that have been featured in high-profile bundles. Those are almost universally really cheap.

mcpixel cards are cheap

If it's to craft, take also account of the number of cards required.

Garry's mod, awsomenauts, civ 5

Terarria was cheap, bought the cards without having the game soo

Brutal Legend, 0.08

Cities in motion 2 badges were my cheapest so far. I got 5th level very fast, each set about 40 cents. :-)
