Idle master doesn't give you the cards, Steam does, Steam gives you half of one badge set only*.

Idle master reads your badge page, linked here, it looks for 'card drops remaining'

Example:
http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=949650073

You need to buy the rest or trade for them:

Free-to-play games do not drop cards unless you spend lots of $€£¥ on in-game purchases or DLCs

For a guide on where to get cheap games, see my profile.

*No, Steam will not give you more if you sell them, craft them, trade them or turn them into gems.

^ standard answer.
So for CSGO, the more you spend in-game or on dlcs, the more cards you can get.

thanks
