Steam gives the cards(not idle master), Steam only gives half a badge set number of cards.

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

yeah, sorry for bitch'n, it can get tiresome when the same questions get asked 100+ times and people don't look for the answers to their questions 1st, 99% of which are answered in the pinned discussions.

See your badge page for 'N card drops remaining' Idle-Master reads that page.
