I don't recommend running Idle Master while you're also playing another game that's connected to a VAC-enabled server. Doing so is the only possible way that Idle Master could potentially trigger a VAC ban, and it also reduces the drop rate of trading cards pretty significantly. To be 100% safe, please close Idle Master before connecting to a VAC-enabled server. The program itself will never communicate with any of these servers, thus it is safe to use Idle Master to idle cards from VAC protected games.

В большинстве игр количество карточек, которые могут вам выпасть, равно примерно половине набора карточек из этой игры. Например, в Half-Life 2 восемь карточек в наборе — значит, во время игры вы получите четыре.

Steam Achievement Manager can do this for you.

gets bunch of dupes cards for csgo

Most games will drop a number of cards equal to about half the number of cards in that game's set of cards. For example, Half-Life 2 has 8 cards in its set, you can receive 4 card drops by playing it.

Remove those game ID's from blacklist :)

Buy more games, idle more cards.
