Stop being impatient and wait. Idlemaster is not the actual source of the cards, steam is. Idlemaster simply imitates any card-giving games you own and sends a signal to steam saying "Getlow is playing <game>" and then patiently waits for steam to give you cards. Unless you plan to try hack Valve, nothing you can do will speed this process up. Just leave your computer on with idlemaster and go to bed, hang out with some real-life friends, go play on console or play a VAC-less game on computer and idlemaster will quietly go through your list of games until you have no more drops available from steam (then it'll turn itself off).
