Where to get Steam trading cards

Cards drop passively while a game is actually running, roughly one every thirty minutes of playtime, up to half of that game's full set. The other half never drops from play at all; it only comes from trading, the market, or a booster pack.

Every individual card can be bought or sold on Steam's own market, priced card by card. It works for filling in a specific missing card, but pricing and buying a whole set this way means many separate purchases, each with its own market fee.

Crafting a badge, or spending Steam gems, can generate a random booster pack for that game, which unpacks into three random cards from its set. It is not a way to target a specific game's cards from nothing; it depends on already having a badge or a gem balance to spend.

The direct path: a complete set for one specific game, already assembled, delivered as one Steam trade. That is the entire inventory Gameza's bots hold, priced per set rather than per card, so the price and the outcome are both known before anything is sent.
